4U Mobile Game Controller Kit, Cell Phone Survival Game Shoot and Aim L1R1 Triggers and Gamepad for PUBG/Fortnite/Rules of Survival support Android and iOS(1Pair+1Gamepad)

The buttons seriously scratched the screen of my brand new phone. They are also pretty useless as they are not responsive. Buy the black and red buttons you'll find on amazon, they are 10 times better quality and work well.

works really well on the phone

I just opened my package to find that I only have the grpis, which do feel way more comfortable to hold than just using the phone, and I can see that with the triggers this will be a great combination, and make games on mobile so better and more fun, waiting to hear back from the suppliers about getting my triggers sent out too, and I'll update the review when they arrive.*Update*So that same day I heard back from customer services, and instead of asking me to send the grips back and get a full replacement order, they just sent me a gode to get the triggers free as a separate order, which arrived this morning, yay.So far I have tested PUBG mobile and C-Ops, and ai can say it makes gaming on a phone so much easier and more fun, it actually makes me want to play games rather than doing it just to pass some time.My first PUBG match with the triggers was my first PUBG match ever, and in a solo mode I won with 13 kills, I haven't tried without the grips and triggers yet to compare my ability with and without, but I'm pretty sure I'm not going to be that good without them.And C-Ops is a game I have played recently without the grips and triggers, and I can say 100% that they are worth using for this game, even though you only need one trigger for firing as there is no ADS (other than sniper rifles), but my skill increased dramatically when using this setup.I have only rated 4 star as after playing for a little while I did notice my triggers had slowly moved enough to come off the on screen buttons and stop firing, but that's nothing a thin piece of foam padding\foam tape won't fix.(Note, I'm using an LG G6, a slightly thicker phone shouldn't have this problem so much)So in conclusion, I would totally recommend this to any mobile gamer, I'll be using this over my bluetooth controllers from now on that's for sure.
