I have a Motive pressure bleeder I got because of a recommendation on a Mercedes forum I used to frequent. It worked well for my Mercedes except if you put too much fluid in the canister. Being a pressure bleeder, it requires an adapter for the M/C reservoir. Unfortunately, after a lengthy conversation with the Motive folks and measuring the diameter and thread pitch of the M/C cap, they admitted that even though they have dozens of adapters, they didn't have an adapter for my M/C (standard TCS M/C). I was able to make one with an spare M/C cap. It works well though.
Having said all that(!) the Russell speedbleeders are nice and I've heard nothing bad about them.
