I am thinking of installing some speed bleeders and was wanting some input before doing it. Are these thing any good? Lets hear the good, the bad and the ugly comments on this product.

 

They work fine. I have used them, but i removed them and put the original ones back in when i was done, and put them up in safe place I can no longer find I just use the rubber hose in a bottle with some brake fluid method now, wich is almost as easy and much better on the wallet......
