Not that great for the money, to be honest I use this for other jobs now as the plates bend and the nut on the end of the threaded bar falls off so I had to use a longer welled nut to avoid this. I tried to push back a piston and where the plates bend it caused the piston to push back uneven, caused the piston to fail and completely messed up the job. Will not recommend as a piston rewind tool, use the kit tool that comes with different adapters as this is fairly useless unless the piston is really easy (Could you your fingers) to rewind.
