I've had a very poor experience with the Uways. My original two turned into 6 due to their high failure rate and the guaranteed replacement during the first year. I'm now barely beyond the 1-yr guarantee and have one that was still working, although I expect it to quit soon, like all the others.
In that price range (actually less), I'd look at the Bushnell Black-Flash model, although many people have had problems with the Bushnells as well. Basically, anything coming out of China has very poor quality control, and chances are high whatever brand is going to not work properly and/or totally fail within a few months or a year or so.
I think the better way to go is either a homebrew or Reconyx or both.
