I have bought a lot of mobile phone controllers looking for one that feels good. This is the one. I love this controller. It's a premium product that just feels good. The thumbsticks have nice textured grips with tight deadzones. The different configurations make it highly versatile and it folds up nicely for portability. Some online reviews have complained about it breaking or being flimsy – I have not experienced this with my one. The controller does lose points in a couple of areas though. The tablet holder can't hold anything bigger than 7", which is basically as small as a tablet can get without being a phone. If it went an inch or 2 bigger, it'd be great (that's what she said). Even then though, the tablet holder doesn't fold up to become as portable as the rest of the controller, which makes it kinda impractical unless you just want to use it around the house. Another issue is that the GameSmart clips for the keyboard and ‘brain’ attachments are difficult to disconnect, to the point that I was scared I was going to bust the controller pulling it apart. I can see how other people have damaged their controllers. Very nerve-wracking. The mobile phone cradle is great, but attaches via a screw- Which feels unnecessarily dated. But, as I said, even with these faults I love the controller. I mostly use it with the keyboard attachment on my tablet, but it is easily the best mobile phone controller I've used. The iPega 9087 Red Knight is the second best, and at only $30, it may seem difficult to justify the price jump to the Lynx 9. The Lynx feels like an artistic prototype tech demo brought to life though. You're not just getting a good controller – you're getting something that was too beautiful for this world and will no longer exist once stock runs out, since they don't make it, or anything like it, anymore. I wouldn't have paid full price for this controller when it first came out, since it went for $400–500AUD (:O). But at $100–150 clearance prices, it's a pretty little piece of gaming history with a great deal of function for any mobile gamer.
