Soo far soo good. I’ve only used the small the small rim brush and I like it. Easy to clean the back of the rim since you can bend the brush.The product is not worth what you pay for at all.These “off brand”’brushes have performed excellent so far. I have three different sets of wheels to clean, all different, and these brushes are so versatile, I have no problems! with any of them! I don’t know how they will hold up, but so far, very pleased!Love the product my wheels have never look cleaner I am a senior and my back is bad so these handy little things make my life a lot easier when it comes to cleaning my wheels I highly recommend them and at a good priceCleans well in tight placesGets in all the nooks and crannies. Great tools.
