I have tested every serious extender on the market, and RestoreX is the one with real trial data behind it. That matters, and this page says so. It also says where a $525 medical device is the wrong buy. Checked line by line against both makers’ own published material.

Read this first
If you have Peyronie’s disease, or you lost length after prostate surgery, buy the RestoreX. It was invented by a Mayo Clinic urologist for exactly that, it is the only traction device with a randomized controlled trial behind it, and its counter-bending force is built to target a curve. Nothing we sell is designed for that job and we are not going to pretend otherwise. Talk to your urologist.
Everything below is for the other man: the one with no medical condition who wants to add length and train consistently for a year. That is what the Epic Extender Pro is built for, and on that job the comparison looks very different.
Every row below is something you would notice in a real session, not a line on a spec sheet.

One is a clinic device you use for half an hour and take off. The other is a training device you wear while you get on with your day. Neither is wrong, but they are not the same purchase.

What one session actually looks like
Seat the vacuum cup and clip it into the base.
Your focusOne step
Wrap yourself with the self-adherent wrap, close the clamp on it.
Seat the pelvic ring against your body so it has something to pull against.
Your focusWrap, clamp, ring
Turn the rods until the screen reads the number you want.
Your focusAn exact figure
Advance the device until white bands appear. That means you are in the zone.
It is a range, not a reading, so two sessions are never quite the same.
Your focusSomewhere in a band
Padded base and angle straps, worn for 1 to 4 hours under your clothes.
Your focusGet on with your day
Thirty minutes, sitting still, then take it off. An hour a day at most.
This one goes to them. Their own trial says more than an hour adds nothing.
Your focusHalf an hour, done
The app already has your tension and your minutes.
Your focusNothing
Nothing is recorded, because there is nothing to record it with.
You write it down yourself, or you guess next time.
Your focusA notebook
Wash the cup and you are ready for tomorrow’s session.
Your focusSoap and water
The self-adherent wrap runs out. Their shop sells five rolls for $30.
Longer rods are $40 a pair, or $65 with a pelvic ring.

RestoreX, RestoreXL and PathRight Medical are trademarks of PathRight Medical, Inc. The product shown on the right is theirs and appears here only so you can see the two designs side by side.
Every part of it exists to fix one of the four reasons men quit extending: guesswork, discomfort, no record of what you did, and no idea what to do next.
This animation shows the Epic Extender, not the Pro. It is our lower priced model, built the same way but without the screen.
Your exact pull on the screen, in kilograms or pounds. Set a number, hit it every session.
Two anchor points for the angle straps, so you can wear it in any position.
Marked in both units and adjustable as you go, with longer rods there as you grow.
The wide soft base that sits against you, so a long session does not end early.
Five sizes in the kit. A leak-free hold for the whole session, with no wrap to buy.
Draws the vacuum in the cup in a couple of squeezes. Nothing to clamp shut.
Four of them, so you can pick the fit that is comfortable rather than the only one you were sent.
Sticks to itself and not to you. There if you want extra grip on a longer session.
And none of it is left to you to figure out
Every extender comes with the free PE Trainer app, the full video course and real support from our team. You get the routine, the technique and someone to ask, so you get the best results in the shortest time instead of guessing your way through the first six months.

100% easy to use extender. Brilliant design, awesome quality & construction. I have been using the penimaster pro, but this is so much more for getting the right tension. 100% money well spent. Currently stretching at 2.5 kg comfortably.

Después de comparar varios extensores, este ha ganado en todos los aspectos, sin lugar a dudas. He comprado algunos accesorios y estoy deseando ganar un par de centímetros. Ahora mismo mido 20 cm. Iré actualizando a medida que pase el tiempo.

The customer service is great! I had an issue with the display on the extender and they sent me a completely new one even after I offered to change the top peace out if they mailed it. Thank you epic extender team!

Haven’t tried any other extender but right away with the digital scale doing one hr every day able to pull at 7.5lbs off the bat just because how comfortable it is! starting size bpel 5’ length x 5’ girth, maybe a year or more I’ll see some improvements.
Five rounds, for the man with no medical condition who wants to add length. Here is the card.
Round 1Knowing your exact tension
A digital display on the device, in kilograms or pounds. You set a number and you hit that number, every time.
They do give you feedback, and we are not going to pretend otherwise. White bands appear when you are inside the treatment zone. A zone is not a number, so you cannot repeat it exactly or progress it in steps.
Round 2Doing the same session tomorrow
The free app logs your tension and your minutes over Bluetooth, then hands you a day by day plan and the full video course.
There are no electronics in the whole device, so nothing is recorded and nothing carries over. You keep the record yourself or you do not keep one.
Round 3If it turns out not to suit you
180-day money back guarantee. Six months is long enough to actually find out whether a traction routine is something you will stick to.
Their own return page says it plainly: due to federal health and safety regulations governing medical devices, all sales are final. On a $525 device, that is the whole risk on you.
Round 4What you actually pay
$379 for the Pro, with the rods, the cups and the app in the box. Epic also sells cheaper models with fewer features, from $199.
$525 for the RestoreX, or $449 for the RestoreXL. Longer rods are another $40 to $65 a pair, and the self-adherent wrap is $30 for five rolls.
Round 5Proof that it actually works
A private community of over 5,000 men, and documented before and after results from them. Up to two inches of length, and up to an inch of girth once the pump is added. It is not a clinical trial and we will not call it one, but it is real evidence from real users, photographed and measured.
Invented by a Mayo Clinic urologist and the only traction device with a randomized controlled trial behind it, published in the Journal of Urology in 2019. Different kind of proof, and a strong one.
Final card 4 – 0Four rounds to Epic Pro, one even
Up to two full inches of permanent length is possible, and the average gain our buyers report is about 1.6 inches. Length built through traction stays. Most men also notice much better erection quality along the way, harder and fuller, and that shows up long before the inches do. The verified buyers below are the ones who kept turning up.

RestoreX say all sales are final, because their device is regulated as a medical device. Epic comes with a 180-day money back guarantee, and a damaged or faulty unit is replaced free.
It depends entirely on why you are buying. RestoreX is a medical device built for Peyronie’s disease and for length lost to surgery or illness, and it is the only traction device with a randomized controlled trial behind it. For those men it is the better buy and we will say that all day. For a healthy man who wants to add length, the Epic Pro is ahead on four things: a digital tension number instead of a zone, an app that logs and plans every session, $379 against $525, and 180 days to change your mind instead of no returns at all.
RestoreX, and speak to a urologist first. It applies a counter-bending force aimed at the curve itself, which is the part that matters for Peyronie’s, and that mechanism is what their trial tested. The Epic Pro pulls straight and is not designed to correct a curve. We would rather lose the sale than sell you the wrong device.
No. Their return page states that due to federal health and safety regulations governing medical devices, all sales are final. They do carry a 12 month limited warranty that covers a defect in workmanship or materials, so a broken device is replaced, but a device that simply does not suit you is yours. Epic comes with a 180-day money back guarantee.
It shows you a zone, not a number. Their Optimized Traction Zone works by white bands appearing on the device once you are inside the therapeutic range, and you advance it without taking it off to stay there. That is genuinely useful and better than nothing at all. It is not the same as reading 2.5 kg on a screen, saving it, and adding a little next month.
This one goes to them and we are not going to argue it. Their protocol is one or two 30 minute sessions a day for 12 weeks, and their own FAQ says flatly that there is no benefit to more than an hour a day, confirmed in their Mayo Clinic trial. The Epic Pro is built around a different idea: comfortable low tension worn while you get on with your day. Pick the one that fits your life, because the routine you actually follow is the one that works.
The silicone sleeves do. On a regular routine of an hour or more a day, expect to swap them about once a month, often longer, and replacements are cheap. Everything else, the cup, the rods, the base and the display, you keep. RestoreX has its own running cost: the self-adherent wrap is $30 for five rolls and comfort pads are $15 for ten.
$525 for the RestoreX and $449 for the RestoreXL, against $379 for the Epic Pro. You are paying for the clinical development and the trial data, which is a real thing to pay for if you have a medical reason to. Longer rods are another $40 to $65 a pair on top. If you want the Epic build without the digital screen, the Epic Extender Full Set is $259, the Best Extender V5.0 is $256 and the All Day Stretcher is $199.
With RestoreX, yes. It is FSA and HSA eligible with a prescription and they publish the HCPCS code E0201 for insurance claims, though they note that insurers and Medicare have no specific coverage for it. Epic is not a medical device and is not FSA or HSA eligible. If paying with pre-tax dollars matters to you, that is a real point in their favour.
Both RestoreX devices were listed on backorder when we checked, shipping two to three weeks after purchase for the RestoreX and three to four for the RestoreXL. Epic kits ship from stock. Check their site before you order, since backorder status changes.
With the Epic Pro, start at 30 minutes a day on low tension for the first week, then build gradually towards 1 to 4 hours. Stop immediately if you feel numbness, pain or a colour change. With RestoreX, follow their protocol and do not exceed 30 minutes in a session. Traction works through consistency over months, not through pulling harder, which is exactly why knowing your real tension number matters so much.
A number, not a zone
Digital tension on the device, every session logged in a free app, and a 180-day money back guarantee. Cheaper Epic models are there too, from $199.
