Are these Can Toppers any good?

This is a quick look (or a review) of the Anko can toppers from Kmart, they are made to fit most 375ml cans, they are washable and reusable, providing protection from insects and spills.
Available cheaper at various outlets including Ebay, Amazon, Aliexpress and Temu.

I had some similar they weren't screw on, the caps flipped.. the screw top probably would ahve been better, but they did keep things out and was able to drink ok. Mine snapped on too, but yeah, they take some 'effort' sometimes.
