Just when you think you have everything you need, they come. These grips add to the feel of your controller, but I felt like it wasn't enough. I'll try cleaning them up with something and hopefully this will increase the grip. However, as everyone says, they stink. It wasn't bad, but definitely noticeable. They are not very difficult to install. Here are my pros and cons: Pros: 1) Adds (some) traction to your controller (see cons below). 2) Easy to install. 3) The sticky material seems strong enough. keep them, but it wouldn't be necessary to hire the Hulk to remove them. Cons: 1) Could have been grippier (definitely why I gave them 2 stars) 2) Smells bad initially 4) Price. I found almost ten bucks to be a bit much for a piece of gum with a sticky material on the back. Especially if they weren't too grippy out of the box. If they improved the grip and shipped two pairs I would probably pay $15 for two. Anyway, $10 without a lot of clutch isn't that great. Conclusion: Not that great for the price, but I'll clean it up and update the review. I'm not holding my breath. Try something different for $10. 2 stars for the lack of grip and 1 for the price.
