I know they are cheap, but I am so peed off at having to buy new brushed because the ones I get keep snapping. And it's always at night so I can't go and buy another - yep, you've guessed it, another one has just snapped! I use the Tommee Tippee brushes as they came with the first steriliser I bought, and although it cleans really well, they are not very durable at all. I'm on my fifth! Does anyone know of a make of bottle brush that's a bit stronger??
