I have one just like this, but it's even more generic/unbranded. I think I paid a little less than this too. It's been pretty rock solid, and I mostly use it to gather known goods, then compare suspected bads.
It goes up to 50ish in/h2o, then you can switch to a standard vacuum gauge after that if needed.
