Muc-Off Chain Brush

Really good product, I used this after the winter period, I keep my bike covered but outside so the chain had picked up some rust. Along with chain cleaner and lubricant this brush took the rust right off and it looks new again. I would give this product 5 starts but I haven't had it for long and don't know how durable it is but so far the bristles seem strong and there is no distortion.

Does the job, just want to see how long bristles last before giving a 5 quick delivery
