One out of three isn't very good odds

anonymous September 2, 2026

This is the only thing I ordered that came on time and was the right item and I damaged. I was happy with this item only the other two were really bad.

Haven't opened it yet so I really can't say much. It looks like it'll do the job, though.

Not bad for what it is

Brandon November 3, 2024

If ur trying to flush system an want to catch every drop of fluid this is a must. If ur using buckets sn drums this may be more trouble than worth. It's good quality an comes with more than enough an extra fittings to be compatible with most cooling systems

I bought this because I thought I needed it to flush a radiator, but I just didn't know any better. Turned out to be completely useless for my vehicle. Perhaps other types of vehicles are able to use this somehow. For me, it was a waste of money. But it didn't cost that much and it was my fault for not knowing what I was doing, so I can't give them a horrible rating.

Wal Mart sent a broken kit missing parts

Jason April 13, 2020

Obviously had been returned at some point and was "repackaged" with packing tape. Was missing parts and was loose in the box when it arrived. Couldn't return because....it was missing parts.
