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.
