An OK deal for new irons. I've seen better sets of irons for similar prices, but not in this category.
These fit into the "Super Game Improvement" category of irons. They're designed for the high-handicapper, someone who struggles getting the ball up into the air with irons, hitting it consistently, hitting shots fat/thin, and/or someone who has a big slice.
The top line of the irons is pretty thick, the face / head is large, and the sole is pretty wide. These features can inspire confidence in players and help provide consistency. Bigger face = larger sweet spot (or more forgiveness) = shots that missed a little on the face fly similar distances and directs. The sole is wider to prevent it from digging into the turf, so if you make "turf first" contact, the club sort of 'bounces' and contacts the ball without 'chunking.'
Taylormade has a specific shaft that's paired with with these irons. They are a pretty light 85g shaft that launches the ball high. The lighter shaft aids in getting swing speed up a little promoting more distance. The fact that it's a high-launching shaft helps the ball get up in the air, something that high-handicappers tend to struggle with. Oh, and the shaft on the AW is slightly heavier at 105g.
The clubs have a lot of offset - the leading edge of the face is behind the shaft. Offset moves the center of gravity of the clubhead, helping golfers who slice to square it at impact. In addition, the offset gives a bit more time to square the club face at impact, again, helping those who slice.
As previously noted, these clubs have some pretty strong lofts. They are about a club stronger that the irons that I play - the 4-iron from this set has the same loft as my 3-iron. Naturally, you'll hit each club a lot longer than you're used to. Unfortunately, you'll have to fill the gaps on both sides of the irons appropriately; maybe with a 17 degree hybrid and a 14 degree wood, or something similar on the low end. Looks like the PW is 45 degrees, and the AW is 50 degrees, so you'd want 54 and 58 degree wedges perhaps. Just something to think about.
Also, if you do purchase these irons, please bring them to a fitter for a proper fitting. They can adjust the length and lie angle to fit your swing. This makes as big of a difference as just having new irons. Standard lie/length doesn't fit everyone. Even if you have been playing standard for a while, it's worth it to make sure it's still a good fit for you.
