🚗 MMonDod Car Engine Piston Ring Installer Removal Kit - Efficient Piston Ring Compressor and Adjustable Installation Plier Set Review

The ring expander itself wasn't really needed, but the compressor was absolutely necessary. I'm definitely glad I packed them together

You got the job done. This is probably not the best choice for a professional engine builder. But do-it-yourself projects here and there. Pretty good for a reasonable price.

Ring compressor ratchet fell apart when compressing the rings. I was restoring a small engine so I used a hose clamp as usual. The pliers were ok.

Inexpensive. Wouldn't buy again. One of the rivets on my 8th piston broke. Luckily I managed to stick it in the block but after that this product became junk.

Ring compressor was in working condition. Job done but looks like it was made cheaply and will likely fail on the rivets that attach the clamp mechanism. But the right price.

Thing is inconvenient to use. If you use it for 1 or 2 jobs that's fine, buy a good one if you use it a lot. I ended up damaging the oil scraper ring on 2 pistons during installation. So have an extra set of rings ready when assembly performance is right.

Ring expanders are great but compressor is terrible. The ratchet wheel is too rough and doesn't allow for much compression, and the rivets holding everything together came loose after the first use. I ended up using a 40 year old Craftsman compressor to get the job done.
