Bottle sterilizer?

Hana

Ladies, there is a recent thread here on baby product regrets and one of the frequently mentioned products people regret getting is the bottle sterilizer. I recently got one, only because it came free with my breast pump. It was never on my wish list for baby buys. Also I do not have a dish washer. I do all my washing by hand in the sink.

Could you share why exactly you regret getting a bottle sterilizer? Also, is there anyone here who actually thinks it is a good product to have on hand?
