First of all, you get two of these! I obviously didn't read the description properly so was over the moon when they both arrived. Originally one was for the husband for his bike, which attached with ease and is so simple to adjust! It is very sturdy and has a taller body than standard drinks holder.
The second holder I attached to the pram. It was to easy to attach to the handle that I could do it! I'm so happy with it! I can pop the babies bottle in when he's finished or (mostly this) I can use it to hold any caffinated drink. Simple things!
In all seriousness though, this product is strong/sturdy and easy to attach.
