They are cool looking! Tbh I never even considered looking for anything other that TT or Avent, prob just because they are the most obvious in shops.
We used TT with Caitlin & she seemed to go fine from BF to them at 8 weeks, Im planing on only BF for a month or 2 and doing combined feeding from 3-4 weeks so have gone for them again. I chucked all Caitlins TT one's out as they had got so worn after 18months use/sterilising. We got a good offer in babies R us with steriliser/btls/btl warmer etc for £60.
