This brush worked amazing with my Nissan leather seats. The seats are about ten years old and were very greasy…. Until I foud Colourlocks brush and mild cleaner which just brought them back to life and gave them this matte brand new finish. I even used this brush on the seats with P&S Xpress Interior Cleaner and it worked awesome. This brush is just magical and really revives and maintains leather seats. The size fit my hands perfectly but it also isn’t too big so it allows you to get into tight creases or areas where cushion meets stitching. The only downside which really upset me however was the wooden construction. After one use I can already see decently sized cracks in the handle. I also stored it face down and made sure to dry it after use but it still ended up cracking. Don't get me wrong this brush will still function and work great, but this makes me wonder how long the brush will last. I would love to see these brushes with the construction quality of Detail Factory brushes.
