I've had the Eco-vu case for about a week now, I really like it. It's simple and elegant. I know there are some very nice cases out there but I'm not prepared to pay big bucks at this time, maybe at a later date.
As for the strap becoming loose, I'm not finding it as big a deal as others but I put a small piece of Velcro on the strap and back, solid as a rock now.
I bought the case on Ebay from a supplier in Ca, they shipped really quick to me in Canada, great service. I'm not going to name the supplier because I've seen their prices fluctuate from $42 ( what i paid) to $139 for the same case.
Well see as time goes by but I'd recommend this case to anyone right now.
