Very Good Tool For Single Track Mountain Bikers
This tool does a great job cleaning the chain. I've had it sitting on my workbench until after ridding a very muddy MTB race two weekends ago. As many reviews have mentioned this process is a little messy - however that is just the nature of a chain moving at speed through and around gears wet with cleaner or soap etc..so just know you are going to put an old beach towel down below your work area and no problem. Also as many reviewers have said a bike stand is very helpful to have to use this tool.I really liked the gear cleaning brush ( I used it with soapy water) to clean out the cassette's cogs. Note however, the plastic pick side of the brush will not fit between the rear cogs if you have a newer 10+ speed rear cassette (mine is an 8 speed and it worked fine).Once I mounted the Cleaning tool on my chain and filled it to the fill line with the provided bottle of the ChainBrite cleaning solution - I started running the cranks backwards and the chain cleaning began. The after photo is what the tools results were. Afterwards cleaning the tool itself was very easy - just take the top off as well as the sponge and brushes assembly and rinse everything out.There are many very good YouTube "How To" videos on using this tool. If you are considering buying this watch a couple of them and you'll know if this tool and cleaning process is for you. For me riding mostly single track trails on my MTB - I'm very glad I purchased it and can keep the drivetrain in good shape.I like that the cleaner is biodegradable, however you quickly realize that the 8 oz bottle will allow you to basically clean your chain only 3 or 4 times unless after use you let the sediment settle and pour off the cleaner at the top back in the bottle. I've looked at the replacement bottle of ChainBrite and it's $13.77 for a 16 oz bottle .... I'm going to try Crystal Simple Green cleaner / degreaser its $13.26 for a gallon.Bottom Line: I like the tool it does a good job - I will try other other biodegradable cleaning solutions that are more cost effective. But I am going to add this to my regular chain and drivetrain maintenance routine.

5.0 out of 5 stars Great value for a handy tool
Reviewed in the United States on July 19, 2017

What a handy, well-made (even in plastic) tool!

I have a 1990 Schwinn Worldsport, which I bought new. I have never (until today) cleaned the chain. Oh, yes, I've lubed the chain, but never cleaned it. Well...

The brush works amazingly well. Even dry, I was able to get it into my 7-speed cassette and get the loose stuff out of there. It worked wonders on my Shimano Exage 300EX derailleur, as well.

The instructions are clear and easy to follow. Affix the handle by sliding it into the tracks on the side of the tool, pop the clips on either end to open the top, fill to the line with cleaner, put in place under the chain, replace the top and the clips, and crank backwards 30 times. Like shampoo, rinse (the tool) and repeat. Wow!

A word to the wise: put some newspaper down under the bike and drape a couple rags over the rear wheel under the derailleur and chain. There is some splatter, and if you have gumwall tires, you know what a pain it is to keep them clean (getting dirty chain oil on them doesn't help) - not to mention that petroleum products and rubber don't do very well together. So, protect your bike and tires (I have alloy rims; I have no idea how carbon fares with this stuff).

Anyway, this is a handy addition to the seasonal tool collection. I'll be cleaning my chain more often. Excellent value for the job it does, and even though it is constructed of plastic, it is molded well and thick enough that it doesn't feel like a cheap plastic tool. Apparently, the sponge is replaceable, as well, so that's another plus. Oh, and once clean, I used the  Park Tool CL-1 Synthetic Blend Chain Lube Bottle (4 oz)  chain lube on it. Very nice.

5.0 out of 5 stars Must have for your bicycle
Reviewed in the United States on April 6, 2017

This kit is exactly what you need if you ride a bicycle. Crazy enthusiast, biker as means of transportation to casual occasional rider, this will make caring for your bike much easier. I NEVER cleaned my chain growing up, so I never cleaned it when I started biking instead of driving. Clean your chains, people! It makes a ridiculous difference when riding! It was SO much easier to ride with a clean chain! With this device, cleaning your chain is fairly simple. You don't have to worry about getting 80000 rags greasy, and filling up buckets and blah blah bla. Just put the soap and water in the little thing, attach to your chain (after you turn your bike over so it's resting on the handlebars and seat) and start pedaling. The best part is that when the mysterious cleaning fluid is gone, you can just use regular soap instead! I have a natural dish soap that I use with just as much success and less worry about chemicals. Do clean the device out after use though, including the removable foam and wire gear things, and set out to dry. Also note, that while it's actually pretty fun to use, the water on the chain will drip on the floor as you're cleaning. In short, this is the most convenient and thorough way I've found to clean my bike chain, and quite frankly, the most fun and satisfying at that. ;)

Brilliant.
I bike everyday to and from work and the chain gets pretty grubby. For years I very sporadically cleaned my chain and often, at the end of the winter after the salt gritters had done their work, would have to replace the chain.

Of course I could/should have cleaned it more often and am sure it would have lasted much longer but it was such a faff.

Not anymore. This is a great product, easy to use and gets the chain pretty clean. Recommended!

Nickel, outil très utile pour dégraisser la chaîne d'un vtt ou d'un velo de route surtout si on est pas chez soit dans son garage . En général, je suis assez maniaque, car je démonte après chaque sortie la chaîne et je la fait tremper dans du gasoil pendant quelques jours ou une journée si je suis pressé et je la passe ensuite au compresseur pour enlever tout reste de résidu (boues, poussières, etc.. ) et aussi m'assurer qu'il ne reste pas de gasoil entre les maillons.
Ce kit me permet quand je suis en vacance de pouvoir nettoyer la chaîne et m'assurer de ne pas avoir de soucis sur mes prochaines sorties.
Decathlon fait aussi un nettoyeur de chaine et vend un liquide pour nettoyer la chaine mais j'ai préférer prendre celui-ci car je pense que park tool connait bien sont affaire surtout qu'il y a eu chez decathlon un soucis sur leur fabrication. Astuce si vous n'avez plus de produit , vous pouvez le remplacer par du liquide vaisselle 1er prix mélangé avec de l'eau.
