not much to say - they do a very good job of cleaning the chain without having to taking it off. They last a while if you wash them out after use - otherwise they warp.
I tried to use this with a Shimano 105 groupset including the short shift rear derailleur. The arm of the cleaner which should sit behind the derailleur wouldn't stay in position; perhaps as a result the chain would not move freely though the cleaner and kept sticking/coming off. I gave up and went back to cleaning by hand. As a minor additional negative, instructions are not particularly well laid out (tiny text with all languages together on the packaging) and the once-open bottles of degreaser and lubricant are not very handy.
Sorry , haven't used it yet .
I bought it without expecting much or having used one of these before. It cleans just fine but the biggest drawback is that it can't be used with the bike upside down. So unless you have a bike stand at home or you have someone to hold your rear wheel while you spin the pedals, you might struggle to use it.
Bought this chain cleaner to replace one that I've had for a long time. Yet to use but its identical to the old one so it'll be good.
I bought this as a replacement for one of the same that I have had for over 15 years. It does a really good job of cleaning the chain with the brushes and then the rubber fins do their best to keep the fluid in the cleaner rather than circulating with the chain which saves cleaning solution. Excellent product.
