AZPRO Portion Control Fuel Pack 18 piece lunch box set with 3 High Performance Interlocking Ice Bricks

I absolutely love this lunch bag. I have used mine weekly for 2 years and it has served me well. I need to have a replacement bottle ready for the one I have now is getting a little “foggy” from daily usage.

I actually bought mine at Sam's Club but it is the exact same except it has 2 drink holders, one on each end. I've had it for a little over a month. I really liked the idea of the stackable containers and ice trays and that everything locked together. Problem is - it doesn't. I only hand wash, but the smallest ice pack won't lock to anything. 2 of the containers won't lock to anything. the middle sized ice pack and largest container are iffy and it takes a lot of work IF you can get them to lock on. Nice idea but very poor implementation. If legos locked together this badly no one would buy them.
