Tommee tippee bottle

I breastfeed and also use a bottle too. The current bottle i’m using isn’t a popular brand. T has a slow flow nipple, but the problem is that is traps air and the nipple goes flat.

I want to get this Tommee tippee bottle, do you use it and if so how is it? Does the nipple go flat or traps air?

The current bottle has the narrow nipple and this one has a wide nipple, will it be easy for my baby to transition?

I know each baby is different and babe might not like it. I don’t want to waste money if it isn’t good or waste a product. I want to be sure.
