After I have tried several other models of bottle and teat brushes and I was not happy with all (especially with low brush of "Baby Love" - Stay away - the wire bracket is so soft and unstable that the teat brush has broken me after only 2 days ), I finally found this great brush of "Nuby" here. I must say I'm thrilled! The bottle brush has much softer bristles than other plus small "rag", so that it really super clean the bottles, while I with all other brushes (including "NUK" -'m sorry, but from this brand I always again on `New disappointed) just had the feeling they would scratch around in the bottles. Indeed, despite repeated cleaning the vials were still streaky, so I had to wipe with a cloth every time and thus so had twice the work. In this brush of "Nuby" but the bottles are really super clean and even if it looks a little big at first, but she's really flexible with her as already mentioned soft bristles and adapts to the bottle (whether wider or narrower) super and cleans them thoroughly! Anyway, I'll just buy more this brush me in the future and can highly recommend them to anyone! Because one or the other euros extra really worth! So: Buy! Buy! Buy!
