Is UV bottles sterilizer worth investing?

I have a Hanil UV steriliser and I love it! It's convenient! It dries and sterilises in 45 minutes. I've loaded 3 feeding bottles, 6 storage bottles, 2 flanges and membranes, plus the teats and bottle covers, to fully maximise the space in the steriliser before switching it on. I've put baby's toys, especially her teethers in the steriliser and it's clean and dry for her to use. If you're planning to get, be warned that the ones on qoo10 comes with Korean manuals only.
