I love the shape, texture, clicks, and most importantly the weight. Improved my aim by 10% accuracy on Overwatch with Widow and Anna.
The only reason I haven't bought a PMM Mouse up until this point is that they have had Logitech internals and switches.
To my knowledge, this is the first all-razer internal(sensor/switches/board) mouse they have made and it is 100% worth it.
If you read this PMM please make a Razer Internal version of P-GP S "ELITE" [10% SMALLER SUPERLIGHT] and email me I will buy it.

Top mod, internals installed by Razer Orochi V2 fits comfortably in the hand (fingertip)!
The assembly was quite easy according to the mod kit instructions.

The weight is now from 60gr down to completely 44gr !!
I'm very satisfied, gladly again :-)

Smoother and a bit faster than InfinityMice sapphire skates (most likely due to different edges), great glide as expected of sapphire, using them on Hien MID, Strider and TigerEsports EBA.

I was expecting this mouse to be uncomfortable to use. I had always been accustomed to larger, heavier mice and was expecting a grow-in period. I was so wrong. It hasn't changed my grip style at all. It is light in the hand, responsive, and made from comfortable high-quality materials. For me it was perfect. Very happy customer. 10/10

Ordered myself the modkit P-VP S. Shell feels incredibly well built (especially for a 3d printed mouse) while still being really lightweight. My mouse measured in at 50g, which is even 6g lighter than their quoted weight. The texture of the mouse is quite rough, but it makes it really nice to grip. The modkit comes with everything you need (even a nice screwdriver too), and the instructions are incredibly detailed/well made. Highly reccommend, especially if theres a dream mouse shape you want in wireless form :)

I've always used ergonomic gaming mice ever since my first proper gaming mouse and to me shape is very important, I now also realised how important the weight is too, to me this is the most comfortable lightest gaming mouse I've ever used.

I ordered a P-SL S (solid) on sale on a whim and I am beyond glad I did. The building process was incredibly easy and actually fun! The material on the mouse feels grippy yet soft, there is no flex or creaking or any build issues. Clicks are crisp, it uses the same scroll wheel, sensor and side buttons as the g305 which are top notch. I couldn't be happier with my performance out of this mouse. It feels beyond good to have the starlight shape at such high quality and relatively low cost. I cannot recommend PMM enough.

This mouse (P-SL S) has been my go-to for numerous months now. Its design exceeded my expectations the first time I got it. The mouse is very lightweight and it has a grippy texture, making it my dream mouse for competitive play. I cannot express how amazing the mouse is.

There was a mishap in the beginning as I am not an expert on mice, however the support were fantastic and tried to help me solve my problem. Due to my incompetence, the problem persisted, however PMM was kind enough to send a replacement and this one has had no problems whatsoever! The mouse gets a 10/10, and PMM gets a 10/10! If you're in need of a mouse, this is your last stop.

Honestly I feel like PMM Make some pretty solid gaming mice.
I own a Prebuilt and a Mod-kit.
Prebuilts ship out of Germany/EU Area and Mod-kits ship out of China Area.

I have a review on "Kyle Ireland Tech" over on YouTube with a break down of; features, issues, software and side by side mice comparisons.

The P-GP S - 10% Smaller Superlight / G Pro comes with everything you need and the instructions on PMM Mods website are really well put together.
I would maybe add some extra foot notes in some spots but other than that it is straight forward.

Feel;
The print feels a bit grippy compared to regular mice, the 3D Print has a slight texture to it so it is a bit grippy.
Some may not like this but most should be fine.
It sits and fits comfortably into my hand.

Quality;
Honestly everything fits together fine and there is no flex at all, very little if any.

Thoughts;
A really well put together mod-kit which should be quite easy to put together if you take your time.
Nice in the hand.
You'll be very happy with it and the hotswap feature is really nice, you can purchase some of your favourite switches from PMM or elsewhere and pop them in.
My Final/Ultimate 10% Smaller G Pro has; Kailh GM 8.0 Switches at the moment and CryoMod Sapphire Skates.
At the time of my review you can pick up the same if not similar Skates from PMM under > Extras > Skates > P-SP1

Honestly if you have the budget go for a Prebuilt or Mod-kit as they are great.
My UL2/Starlight S Prebuilt has soldered Kailh GM 4.0 Red switches on the main clicks and the sides.
G305 Based Mod-kits are hotswap, prebuilts are soldered.

Prebuilts come with extras; A Carrying Case and some Grip Tape.

Notes;
*Be careful with the spring battery wires as if you break them you will have to solder, you'll be fine if you go slow.
It comes with spare wires if you mess up and need to solder.

*If you get a mod-kit be sure to note that you may or most likely will have to make some holes a bit bigger with a screwdriver to fit the hot swap slots, they do note this in one point of the instructions.

I´ve bought the P-305 (Pre-Built) and needless to say; I am loving it! The print and overall quality is extremely good and everything worked great as soon as I took it out of the package. Everything is on point and the experience over the past days was just a dream.

I definitely recommend it!

Got the pre-built XM1 after 3 weeks, the quality is really great and much better than expected. It's my new main now for sure, the grips that it comes with are great but not necessary because of the grippy surface texture. You can squeeze the sides a decent amount and flex mostly occurs near the front, unless you deathgrip your mouse, I can see this lasting as long as regular mice. The clicks are lighter than expected especially for Kailh 4.0 but it actually feels nice. The clicks are way better than I expected and I thought it would be the weakest part of the mouse.

I played well after my first game with it earlier today and performed well, it felt amazing and the skates are great. Might get a new modkit once they release a collection with no holes.

Definitely recommended.

The P-CBR has instantly become my main mouse. I’m typically a claw grip user but found the fingertip grip on this mouse to be easy to adapt to. I’m aiming much better in Valorant with this mouse compared to my other mice. Despite the small size, I have found this to be very comfortable despite my larger hands (19.5 x 11.5cm). I found this more comfortable than my modded Mz-1 wireless. The Mz1 would cause wrist pain after an hour of use, whereas the P-CBR has allowed me to play pain free. I got the mod kit version and the instructions were easy to follow. The only tricky part was breaking the battery plate, which took some extra cutting afterwards for it to fit into the battery slot- but not overly complicated. Took me a total of about 30 minutes to build from start to finish, including g the time it took for me to take apart the Orochi V2. Would highly recommend this mouse !

The P-CBR mouse. Goated fingertip wireless. If you’re talking about pure gaming performance (and here really should be no other criteria when buying a mouse) I Prefer it to my gwolves HSK+ And finalmouse starlights (similar weight range and small size)

Such attention to detail on this high quality product. Instructions made it a breeze to build (mod kit).

I was skeptical about trying a 3d printed mouse shell. But this blew my mind and I will maybe buy another one from PMM even though this P-CBrR is my “end game” or maybe wait for the 8000hz wired version (please make the wire come out of the BACK of the mouse ! Optimal ! )

PMM got a life long customer now (for when I can afford my next mouse!)

I really love the mouse. The build quality is good. a bit of side flex when I squeeze the sides hard but no one would do it this hard during use. Side buttons don't click no matter how hard I sneeze. The main clicks feel nice and the tensioning system is awesome. There is a little bit of side to side play when you hold down the clicks but not enough to effect you in game. I didn't notice until I tested for it. As someone that absolutely hates holes on the sides, I love these ones. (shocking) ;) It's the first mouse with holes on the sides that I have tried where the holes don't impede me trying to grip the mouse and actually help by providing better grip texture and ventilation. I think it's because of how narrow they are. Awesome design! The kit in general was very easy, quick and fun to put together with the instructions provided on the site. If there is a shape here that doesn't have wireless or is too heavy for you I really recommend it. =)

Great product and fast response to questions/inquiries if any help is needed during assembly which was straightforward. Shape feels 95% similar to the original. Main clicks feel good but I ended up using lighter switches, having hotswap sockets make changing them easy. Provided battery has good lifespan. All in all, glad I decided to get one, 25g makes a very noticeable difference.
