Don't rate it bad because you did not use it in right way.

It's a scrapper brush and not dirt-magnet that it will pull away dirt stuck in chain grease. Once you brush the chain properly use a cotton rag cloth dipped in kerosene oil to hold the chain with moderate pressure and revolve the rear tire. All scrapped grease and dirt will transfer to the cloth and that completes the process.
Edit after 1st use: What an excellent brush. I used a small spray bottle for spraying kerosene to clean dirt and lube stuck on chain. The chain looks like brand new now. I also ordered a Motul C2 lubricant which I apply after cleaning.
People are complaining about built quality. It's hard plastic with very durable bristles. Please don't use accelerator to move your bike chain and sprocket . It is dangerous for both your hand and this tool. Just put in on chain and slowly revolve rear tyre while in neutral gear.
It will not break if you use it properly. Quality is good enough and if it breaks due to improper use , you can easily fix using feviquick. Go for it don't trust negative comment where people don't know how to use it.
