This is the best bottle brush out there!! I have tried several and searched everywhere for something like this. I am amazed that this is not a more popular and standard product. The bristles are super strong and hold their shape without bending and they dry really fast. I've had mine for 2 months and it still looks like the first day I bought it. The nipple brush is awesome and cleans better than any nipple brush I've seen. So far, I don't think I'll ever have to buy a new one down the road to replace this as it gets older because it's such great quality. The other brushes I've tried with the sponges attached on the end, wore out in like a month (not to mention, all the bacterial growth. Yuck!). I will definitely be buying this for every new mom I know!
