It's a lot better than nothing. At this stage I am not wild about chinese quality in general either. I suspect it is simular to japanese quality when they first entered world markets. A few years from now chinese quality might be good. Then you will really pay. But for occasional use what the heck it's a throwaway price. A member grabbed one for me some time ago as I could not resolve shipping to canada in a satisfactory fashion with them. That gesture was appreciated. I also believe the catalogue price is a few dollars cheaper. If you want to check the archives. Hudson's sells or was selling the same thing for 9.95 I believe. This compression checker is probably just fine for light duty use. Diesel compression checkers have not been historically really cheap mind the adapters this one has. Even the box is pretty decent everything considered.
