Bought BBT-29 along with a Park Tool BBT-47-16. Was happy with the BBT-29 because it can be held in place with a bolt and some washers. However, it is hard to get a good grip with the BBT-47-16. Depends on application but may want to get two BBT-29's instead of one BBT-29 and a BBT-47-16.
Not the best tool I've owned and can be a little abrasive on the BB cup as it likes to slip off.
