I bought the handle after I noticed that my baby wanted to hold the bottle by himself. Easy for him to grab & hold the bottle without waiting me to do it for him. The handle hold the bottle tightly.

But it's thin and easy to break if it's wrongly removed. I broke one before while taking it off from the bottle.
