I purchased the Bluerex / Roocase and was not satisfied with the level of protection that it offered on all the edges so I decided to modify it to work with a TPU skin.
This was the skin I got - $10.99 + shipping
Using a heat gun, I reformed all the edge catches to wrap around the skin, and also slightly modified the closure to be easier to close / open.
After the first round of mods, I noticed that it slipped *just slightly* when opening it up to use the case as a stand, so I used my dremel and removed small areas that matched the coutours of the two side catches.
One more round of the heat gun to form the side catches a bit tighter and...Turned out great! I can still pull the tablet (still in the skin) out of the case if I need, and it is captured very solidly while being used in the case.
Overall I am very happy. It adds just a bit of weight because of the double layers of material, but...I tend to be hard on my equipment so the extra protection is Definitely worth it.
In a few days, I may buy the 360 rotating case and see if this mod works as well! Thanks for your time!
P.S. Apologies for the slightly blurry last pic - It shows the removal of material that allows the side catches to lock into the skin. This is also before I cleaned up the spot where I removed the material...the finished piece is Much Nicer..
