We used techniice for a while when we bought an ice box from them. The ice box was/is fantastic but the ice brick/cube things seemed to leak a little and we had some residue on stuff we and we ended up throwing them away. The ice box on its own with normal ice is really fantastic anyway.

We have 2 eskies, one 60 litre, one ordinary bbq size. Went to Karumba from Brisbane , put large block of dry ice in the 60 litre esky. along with bags of ice. Transferred ice to the small esky as needed, still had dry ice when we arrived at Karumba.Would have needed more dry ice for the trip back if fish were involved, from what I have been told, the techni ice takes the place of bags of ice quite well, Bob
We use techni-ice at work for keeping intra-venous fluid cool. The stuff is used in the same way as a freezer block and with the same effect, an advantage is that the flexible sheets can be wrapped around items or shaped to suit a container. When thawed it oozes a sticky, gooey residue.
We have been using it within standard eskies for a couple of years now, it does everything they say. I tested it when I first got it and it stood up to manufacturers claims. Would love a 'proper' ice chest (as they also sell) but honestly haven't needed it as yet.
Recently, I have been adding a few of the old fashioned blue ice block bottles to get an extra day or two out of it when family camping. Not sure if this helps, but it makes me think it does so hence feel good about it too!
The techi ice might indeed stay cold for a long time...but... is it efficient at absorbing heat from a warmer "body" thereby cooling it? Alternatively they've got some goo inside the pack which has a different "specific heat" from the usual glycol stuff and therefore requires more heat input to raise its temp. etc etc.
Frankly all that screwing around with ice bricks (other than to keep the beer cool for a SHORT drive) is why I bought a "bushman"...
