Review on Enhanced FIRSTINFO Hydraulic Brake Bleeder Tool with Lockable 🔧 Hose and One Way Check Valve for Efficient Brake Fluid Bleeding by King Reeves

I've seen some reviews saying the end piece doesn't fit the bleed nipple snugly and that the end was made for longer nipples. The first thing I did was attach it to the drain nipple and of course it was loose and just moved. I disassembled it and saw a long rubber insert that was supposed to fit on the end of the nipple. I put it back together and then screwed the latch down and checked how far back the gasket is. The tighter I made it, the closer the gasket was to the hole. I ended up getting it close enough to the hole for it to seal perfectly on the nipple. That's all it took to tighten the front threaded mount! The company's fault is that some simple instructions were not included, otherwise I gave it 5 stars.
