Was surprised at how light this thing is. Like holding air. Not sure how long it will last as it is so not there if you know what I mean. That being said it works quite well and appears to be accurate after testing it against three other sources. The red back light is cool and needed for low light situations. Well worth the money I think, and would buy again. The slime products are all worth having. I keep the liquid slime in the trunk with a black and decker power station for jump starts and airing up tires.
