They have good reviews, so it is a good start.
I have to wonder; when they decide on the length it will hold ice, how often do they open it, and what ambient temperatures are they conducting the tests in?
In real world use, it may be opened 10-15 times a day. If they are testing, and only open it after several days for a second to verify there is still ice, then it isn't really giving an accurate idea of how it will work for normal folks that use it like a picnic cooler in hot summer time conditions.
Not trying to say anything bad about them, just wondering.

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
