I can't own a cell phone without also owning a case to go with it. I don't like carrying my phone without the protection of a case and usually it's much more convenient for me as well. I often leave the house without my cell phone if it isn't attached to my hip so having a cell phone case for me is more or less a necessity - at least as far as my family is concerned.
This Roots case is perfect for my HTC Magic. The phone fits in nicely, not too snug but just snug enough that I know it is safe and secure. The flap of the case has a magnet inside of it and another magnet on the case itself which keeps the flap securely in place over the phone.
The clip on the back of the case clips onto my pants pocket or the waist area and sits there snugly so that I can walk, run and move about without worrying that I'm going to lose the phone.
For $29.99 it's a bit pricey as far as cases go, but it appears to be rather well made and I don't think I'll be wearing it out any time soon. My husband also has a Roots case and he puts his phone through a lot more wear and tear than I do in a day and his case seems to be holding up quite well also. My case wasn't for any particular phone that I can recall but it does suit the HTC Magic quite well.
Overall, I'd have to say that the Roots cases we own are quite decent and the only problem I have with them is that they are a bit pricey but you get what you pay for so I won't complain further.
