It has long legs to avoid hitting pipes/outlets. By adjusting it to fit tightly on the pump ring, it can withstand a lot of torque without damaging the frame or breaking teeth from the ring. For its price, it is excellent. I bought it as a "temporary" tool because the Facom DM.JPB I was using has been heavily damaged by stuck rings on reservoirs, and after about 20 uses, it makes me believe that I won't need to buy another "branded" tool for this job. On the contrary, I will get another one as a spare, just in case...
