Of the 6 reviewers at BGT, the only negative review was yours, Roger, and you had one of the first edition Picnic sets with the snaps instead of the current friction folds.
Other reviewers questioned the stability of the PLATE, due to it's large surface area relative to the low sides, and I agree with their assessment. The bowl however has received generally very good ratings. Yes, the Orikaso items - like the titanium, lexan, and similar items - will tranmit heat. Hence my recommendation for a bandana under it when hot liquids are used in the bowl or cup.
Bottom line - HYOH. My wife, son, and I each have a bowl and really enjoy them. Easy to assemble, disassemble, and clean. Stores anywhere. The unfolded bowl slips easily down one side of the pack, or lies flat across the top. No more rigid Tuppeware or salsa containers for us.
