ECHZOVE Switch OLED Controller Grip, Controller Grip Compatible with Switch or Switch OLED with Gravity Induction of Six-Axis Gyroscope, Double Motor Vibration

At the time of writing this there's just 26 reviews with a some what low rating of 3.7. Unless the quality is really that inconsistent... I don't get it, it's working perfect for me. I like it alot so far and prefer it over my Binbok joycons or my Satisfy grip.
This is the "Oled" model which I think is a newer version than the original model. This one actually comes with add on spacer rail adapters that make it compatible with both the original switch (it's a tiny bit smaller) as well as the newer Oled Switch. I'm still playing on the original V2 Switch and the rail adapters worked perfect with the switch seeming to kind of click or seat perfectly in to place. Seems secure and if the next Switch console happens to follow the Oled format it might work with it?
In fact thats one of my favorite things about this Dobe controller is that the joycons are connected with built in backer plate to make it a one piece solid controller that the Switch docks into instead of having separate joycons hanging off rails on each end. This makes it much more ridgid and solid feeling than my Binbok's or any other two piece separate joycon design. The main reason I bought this is the Binboks felt like they had a little flex at the rail joints which still worked fine but felt flimsy and bugged the crap out of me. Always felt like it might break whether it actually would or not.
All the buttons, analogs and triggers seem fine and work well. The D-pad is clicky but with a definite pivot point that works fine giving a true up, down and diagonal press. Buttons have a felt feed back of being depressed.. like they click with without being overly clicky.
L and R are standard digital buttons. The triggers have a small amount of travel like an analog but are still just digital. Overall travel of a 1/4" to 5/16" of an inch but they feel kind of like a two stage gun trigger. There's a short low resistance stroke that registers a press in game.. and then a wall of resistance that takes a little more pressure for the second stage that then bottoms out. Not sure why its like that but feels fine to me. To me it actually feels like it would be cool if a game utilized a two stage double barrel shotgun trigger, or fire plus grenade launcher.. (two actions on one pull). The sticks are pretty snappy, come back to center good and don't feel like drift should be a concern. They have a small dead zone and track fine in the switch calibration utility (in settings). The sticks do come with various interchangeable grip caps which some are rubbery and some just slick plastic. I picked the two that were closest in size and height and slapped a set of Skull & Co rubberized grip caps on those and all was good.
No turbo buttons but four extra back buttons, two on the back finger grip of each hand that are simple enough to program to duplicate almost any face button or trigger.
Other info to mention is these have standard but good vibration feedback and motion control that works well. For me motion control is a must which makes the Hori split pad pro's a no go for being an incomplete controller with out it. No NFC or IR just like all other third party controllers which personally I don't care about. It does have a charge passthrough and is powered with USB-C... so you can play while charging with the standard switch charger or most any current 15w plus phone charger. The controller's USB-C port is just there to pass power to the Switch's USB-C port. To be clear, the controller doesn't even have batteries, it's just simply powered off the switch. That said it really doesn't seem that taxing on the switch batteries or at least not enough that I noticed as it hasn't interrupted a play session at all. As far as pairing all you do is jump into the settings menu and under controllers turn on the "connect to wired pro controller" feature and your good to go. This is actually just plugging into switch just like any other wired controller, you just don't have a cord since the switch docks directly in to it. Of course a positive side to this is you generally have better, faster and more latency free response times with none of the connection issues that are sometimes possible with bluetooth or other wireless connections.

I guess really that's about it.. solid and simple. No fancy LED lights or confusing macro trick buttons.. just what you need in a solid and comfortable to use format.
I did test this thing out with about 8 or 10 hours of play time before reviewing.
Of course longevity will have to prove itself but the ergonomics, the actual controls and the quality level of the one I received I'm happy with.
5 stars for now.

Perfectly fir my swith and ar comfy for hand held mode.

I looked around a bit at options. I wasn't looking for anything high-end, just something that would fit my hands more comfortably. With the joycons I have to stretch my fingers awkwardly to reach the shoulder buttons. Twin-stick shooters are especially uncomfortable. But this grip feels great in my hands.

- I like the one-piece design that cradles and protects the Switch. It's even lifted up off the table when I set it down, as opposed to the console laying flat on the table. This is a big plus for me, because I shorted out a previous Switch with spilled water.
- All buttons and triggers work fine. The shoulder buttons are larger and trigger with a slight press, though they have a lot of further "travel time" to be fully pressed and then unpressed. A little bit of retraining my finger muscles but nothing serious.
- Very strong rumble function.
- The battery seems to drain a touch faster, as the grip leeches power from the console. But it's not that noticeable and I still get nice long play sessions.

This controller is great and fits my hands perfectly. Gives protection for the main switch unit.

I love the ergonomics and feel of the this remote. The joystick has much more range and feel.
