I was looking forward to keeping the 12 ounce container in my car and the 2 ounce containers in my purse, desk and tote so I would be able to use sanitizer on the go. The 12 ounce container erupted and oozed all over my cup holder ( and I wasn't even parked in the sun) the first day, the one in my tote and my purse leaked all over too. The one I keep in my desk is still full, but the others were wasted and made a big sticky mess. For indoor/temperature controlled use only.
