I have seen these self-unrolling and self-coiling hoses come and go over the years - mostly go.
To do what is says it has to be very thin material, hence your strength has to go way down. Also, it is far more likely to kink when you pull it across the yard, so you should plan on extra trips from end to end of the hose to unkink it.
One other factor is that the inside is going to be very rough which increases friction, so the pressure at the hose end will be much less. Especially in a 100 foot hose, this can be critical - for this length run, if you are going to be hooking it to a sprinkler, you probably will need a 3/4 inch hose to get decent sprinkler operation and coverage, especially if it is a rotating head (rainbird type. I could not find out what diameter this hose it, but I would guess 1/2 or 5/8", those being common gardon hose sizes.
I haenot done a test, but I would guess it is going to consume 10 or so psi just to keep expanded - that is pressure you lose at the consuming end.
I would recommend you check out the reviews on Amazon - just put in blue x dap in their item search box - there are a LOT of people who say it stinks, breaks immediately, comes defective, etc. I certainly would not buy an item with these comments.
Bear in mind also, based on a quick check online, it appears this product is sold by a television marketing company, NOT by the makers of DAP grout, caulks and household chemicals.
