I have these in all my cabinets not sure how well they work though since they are so small

I zap them with 20 seconds and let them cool a bit and continue until the orange color has returned

Dont waste your time on microwaving doesnt work well at all

Many of the products of this general type come in a small tin box with a tiny window to show you the gel balls

Ive tried several of those and its very difficult to distinguish the color of the gel through that tiny window as the tin doesnt allow any light to pass through it

I gave four stars only because recharging it seems to be more an art than a science

Whatever you do dont microwave it for more than 30 seconds or it will start to melt

I bought them to keep 2 small safes dry i keep my hand guns in them but it didnt take long to turn green
