Smart Microfiber System Natural Fibre Mix Dish Brush 5 "Best dish brush" Miss Christie 23 March 2019 I try to use alternatives to disposable plastic wherever possible, which was what attracted me to this product, and I've not been disappointed. The fibers are lovely and soft and as such gentle on glassware but are also effective on the tougher and dirtier parts of the dishes. I'll never go back to the stiff bristled plastic brushes as long as these are available. The handle sleeve is comfortable to hold. I was not able to purchase replacement heads at the same time as they were out of stock, but I have tried taking off and putting back on the same head so can confirm it is a simple process.
