Lives up to the name!

I first got into PE late last year and since I began my journey I've used quite a few extenders such as totalman, penimaster, and even a few budget ones off amazon and aliexpress. I figured since I'm spending extra money on PE I might as well take the full plunge and really go all in with the apparent best! After using the device for the past few days here are my thoughts:

-Tension scale and spinning/screwing:
Having a tension scale is hella convenient! It's nice having actual numbers on the extender that tells you how much tension you're using which is useful so you know how much progress you're making and most importantly not increasing tension too fast and ending up hurting yourself by accident. Most extenders I've tried use the method of screwing bars on/off the extender to make the extender longer and have more tension which can be tedious and there's the risk of you losing the bars or misplacing them. Plus adding a bar can end up with you increasing tension to fast because your member hasn't adapted to the new level of stretch yet. The screw method the best extender uses makes increasing tension gradual which is more more ideal for progressing in PE. It easily allows you to start 4.4 lbs and then gradually increase the tension to 6.6+ rather than jumping from low to high like other extenders. The only main downside to the way the Best extender does this is that the extender is a bit large and not really suitable for wearing under clothes(which is what the best all day stretcher is for so this issue is already addressed) while out unless you wear really baggy pants, which brings me to the next topic--

-Build quality/sturdiness:
The device definitely feels more premium that other devices. While other extenders feel a bit flimsy at their hinges, so far the best extender is holding up quite well! It snaps and holds into place how I need it too and maybe in the future after constant use it will start to give out but I imagine by then there will be a new superior version.

-Adaptability & comfort:
My favorite part of this device and what really makes it the best I've used so far imo. The fat, flat, soft silicone base makes using the device much more comfortable which is super important since if something isn't comfortable you'll not wear it long and you'll dread the times you do wear it. The hard thin bases of devices like penimasters extender and totalman makes my groin feel sore and raw after a while. Due to them being so thin they really dig into your crotch at higher tensions so you either have to wear them until you can no longer bare the pain or wrap them up in something soft and flat to reduce how rough it is on the groin area. The best extender being so soft and thick mean this is a non-issue and I can wear it comfortably even at high tensions.

The adaptability is what really sold this product for me. I have a few different cups I've tried like totalman, screw penis cup, penimaster etc and of all I've tried the penimaster cup is easily the most suitable and comfortable for me and led to no blisters plus is easy to take off/put on quickly unlike other cups that require the water method or taping/silicone cap on the glans so I was happy to see an extender that not only has comfort, ease of use and sturdiness as a priority but the ability to use any cup I want so I'm not forced to use a cup I don't like just because I have a different extender. It really adapts to any cup which is hard not to appreciate!

That wraps up my review! For anyone who doesn't like to read here are the summarized pros and cons:

-Tension scale on the device so you don't overdo it and ability to gradually increase/decrease tension.

-Sturdy and with great build quality(strong and not flimsy feeling)

-Comfortable base means you can wear it long term without too much trouble.

-Adaptable to any cup so you can use your favorite cups with the best extender while still getting all of the benefits.


-Quite large with no smaller size options so not really suitable for wearing under clothing while out unless you wear MC Hammer pants. This is mainly a device you use at home after you get home from work or finish running errands or something your can wear while you work from home.

-A bit more expensive compared to other extenders especially if bundled so don't buy unless you're serious about PE and don't mind paying a premium.

-Cups I personally can't speak on since I mainly use penimaster and don't own the ones for the best extender but they seem like generic cups from what I've seen and heard so nothing too special.

I can’t get the unit to work at all.
I’m doing something wrong with the bell and sleeve’s.

Extender well made but cups don't work.

The quality of the device is very good. Unfortunately I have not been able to use it and after seeing another review I see that others have found the quality of the cups to be sub par. I am waiting for an order of a reputable brand. Can't say anything bad about the device itself. Well packaged and very well made.
