Rated 5.0 out of 5.0 by ProContractor Great Grout!
This is a great product, especially at this price! We have been using this product on heavy civil construction projects for years. We have used this in underwater applications, above water applications, vertically and horizontally. A grout with a break strength at 6,000 psi in 7 days when placed at a flow able consistency typically will cost between $35-$45 a 50# sack at specialty concrete suppliers. We have had this product tested at accredited testing facilities and it performs consistently as specified. Yes, it does have a short pot life when at a flow able consistency. Plan your work accordingly.

Rated 5.0 out of 5.0 by Rug The Grout you want
I have used almost every brand of grout available. This is the easiest to work grout there is. In response to the other guys review about the working time only being 10 minutes, yes that is mostly true. But if you work with enough types of grout, that is actually excellent. Still being able to horse it at 25 minutes is not bad either. Some grouts go from peanut butter to rock in less than 30 seconds, some take 6 hours. This is the best for what I do. Only thing that could make it better is if it was sold in 5 gallon buckets.

Rated 5.0 out of 5.0 by ML220 Good product, but "working time" needs some clarification
I bought this product to level the top of a basement wall prior to installing the mudsill. So I had up to about 5/8" to compensate for. The product needs to be mechanically mixed to achieve a smooth consistency, but a few minutes with a paint mixer attached to a drill works fine. The issue I have is not with the product itself, but with the instructions for the product, which specs a "working time" (where the material will "retain a fluid consistency") of 25 minutes at 50-73degF. I mixed the product to a flowable consistency, weather was mid-50's and overcast, and I had a maximum of ten minutes from the time I began mixing to the time the product took on a plastic consistency. I had to compress it under the mudsill, so after ten minutes I was no longer able to do so. Working 16 feet at a time on an 8" wall, it was nearly impossible to mix and place the product within ten minutes. The product does stay "workable" for about a half hour, but by that point it's well on the way to setting up and is in no way close to the same consistency it was twenty minutes prior. Also, an important reminder: if you're working on a porous surface (like concrete), be sure to wet it down just before laying the grout. Otherwise the surface will suck the water from your grout and render it useless.
