Review on Enhance Automotive Performance with 8MILELAKE 21pcs Handheld Vacuum Pump Set Tester and Brake Bleeder Test Kit by Tyler Blake

I'm a mechanic in a chainsaw shop and use it every day to check the pressure and vacuum in the crankcases of small 2 stroke engines. I've also used it to bleed and change the hydraulic clutch oil on my off-road bike, as well as a number of other uses. It's solid and well built. I'm giving it 4 stars overall because I wish the hardware that came with it was a bit more powerful. Rubber becomes quite pliable in any heat above average room temperature.
