I highly suggest doing some research on starting solids, baby led weaning and other similar topics.
You do not want to introduce any solids prior to 6 mos at the soonest. There are signs that a baby is ready for solids, and you need to familiarize yourself with them. And even then solids are only for practice (learning tastes, textures, etc.) until after 12 mos, they shouldn't be getting any significant portion of their calories from them. Babies do not have the ability to digest complex carbohydrates like grains until some time after 18 mos (this is one reason why rice cereal is a horrible first food). I know I can attest to the food coming out the other end in much the same shape as it went in until somewhere around DS' 2nd birthday. So if that's the case, you can't depend on the solids for their nutrition until after that point.
As for that particular brand, I think I've heard of it. Can't say anything good or bad about it. We went straight to table food, and skipped purees entirely. Purees are not necessary at all, and are often just a waste of money (IMO). We started DS with things like overcooked broccoli or asparagus spears, roasted sweet potato fries, slices of (fresh) peach or apricot, etc. Things he could pick up and feed himself but that were soft enough that they didn't require a lot of chewing.
If the idea of dehydrated reconstitutable food appeals to you though - I'd suggest pricing it out per ounce, and compare it to something like Just Tomatoes, which is freeze dried fruit/veg (stick it in the food processor for a few seconds and you have powder). Or if you just really want to do purees, I'd recommend getting a baby food mill (they're about $10) and just making it yourself and freezing it. An extra few minutes spent a few times a week while you're making dinner will give you frozen purees for weeks, and you know precisely what's in it.
