You get what you pay for with this product. it works, but not well. no sure how long it will hold up for. made from cheap plastic. That all being said, you get what you pay for. If you're looking for a cheap option at checking tire pressure this product will do. I would however recommend spending a few extra dollars and getting a more expensive product.
Works as intended. Light weight, not sure if that means cheaper components but I've had it a few months and never had an issue with it. 0-20PSI, seems to be accurate. Keep it clean and you won't have trouble.
I bought two and they read exactly the same and I tested again an expensive high quality gage I have in the shop and its right on the money. great to toss in the tool bag on the bike it weighs nothing.
