Well to begin they are overpriced way overpriced. I paid $50 for the combo which includes the surface and holster. When you hold it on the side where case is locked if you press it with even slightly pressure it creaks. However the holster is perfect and with surface its good overall coverage. I just think $50 is to much for freaking shell. Also they do sell Innocase battery and screen protector as both been tested over the years and failed compared to the competitors.
I myself would have to go with Mugen Power when it comes to stock size battery and for screen protector anything but Zigg's InvisibleSHEILD as it took me 5sec to put hole in it :P so much for them to claim it was virtually indestructible lol I didn't want to send it back as it would be hard to explain during RMA that why it has hole in the middle LOL what a waste of $30 that was.A lot of company make decent screen protectors now as you just have to know which to get as you can get clear glass or anti glare mostly like Vikuiti's DQC-160 type which is IMHO best.
