If you plug a controller in it disappears and windows starts playing the 'new usb device connected' sound effect. Would not recommend in the slightest.

This works for a lunchbox. Perfect for traveling in a small cooler. I pack two of these in my hubby's insulated lunchbox and they keep his breakfast, lunch and drinks cold until it is time for eating/drinking.

Great product, small, stays cold for a long time. Very effective for small containers and small areas of the body. No leaks so far. Easy hand cleaning.

Only received 1. Random freezer pack goo in your lunch is not great. Makes them odd shaped and worried about them leaking. One lasted 5 months.
