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.

OK - I happened to see this exact item as a featured just-inside-the-door item at Walmart yesterday, for $20 - I would say what a joke. First off, it was 1/2 inch hose not 5/8 (standard general use US size) or 3/4 inch (normally used for 100' hoses), so your flow rates and pressure losses will likely be such that it will adequately run only a very small sprinkler. Might be OK for wandering around and hand watering.

Also, the general construction looked like junk, with tears in the outer covering (although brand new), and two I looked at had damaged threads in the connector and one connector was really out of round, as was commented on in the Amazon reviews - it looks like an award winning example of typical Chinese trash. They had one out of the box on display - I tried stretching it out, and it kinked like crazy. I guess you would have to have a shutoff valve on the outlet end (you can get ones that screw onto the hose and the sprinkler swrews into teat, so you can shut off the sprinkler to relocate it around without soaking yourself) so you can pressurize the hose up to keep it from kinking up, then stretch it out.

I would say forget it - if you really feel compelled to get rid of a 20 spot, why not put it to some good use and send it to Moore, OK tornado relief instead.
