If you're looking for an easy way to cover your HTC One M8, keep it from getting bumped and scratched, or just make it a bit easier to hold here's a little winner for you. The Cruzerlite Bugdroid Circuit case is an unassuming and inexpensive TPU case that will wrap your M8 up and keep it safe from most of what life throws at it.
It's flexible and easy to put on or take off, features a really cool bugdroid and circuit design embossed into the back, and is designed so everything fits and your ports or buttons are all easy to manipulate. It wraps around the front of the M8, giving you about a millimeter clearance between the glass and any surface should you lay your phone face-down — like when silencing the ringer —and it's just thick enough to keep both camera lenses elevated when the phone is resting on its back.
Most importantly, to me anyway, is the extra grip it gives to the phone. The M8's exquisite metal body makes it a very slippery beast. It seems like it's impossible to get a good grip on it, and like you, I hate dropping my phone. This thin TPU case may cover up the sexy aluminum body, but it definitely gives you a great grip when holding the M8. This is the case I would use anytime — and every time — I leave the house with the precious.
