This is a review from the perspective of someone who already owns some dungeons and dragons books (original 3 PHB, DMG and MM) and so the review kind of reflects that to a certain extent this product isn't really aimed at me, but is for all the others out there who are, like me, curious about the new range and wonder if its worth picking up. Although i've given it 3 stars its more like 3.5 (it doesn't let you do that)
This is the second essentials product I have purchased. The first was the rules compendium which has been for me an 'essential' product in that it was cheap, had all the main rules you would require at the table and smaller and lighter than the other books for carrying to said table.
So the dungeon masters book inside the box is very much the content from the original dmg with some extras from dmg 2, so its quite handy in that respect, but at the table I don't have much call for looking up dmg rules as pretty much all the most 'table used' rules are in the rules compendium.
The box is actually a really good selling point, from the fact you can put quite a lot inside i've found it useful just as a means of taking stuff from A to B and keeping all the little tokens and such handy.
The good:
Very high quality printed tokens and full colour adventure booklet although I haven't played it as I run a Dark Sun campaign I may steal some encounters from it and adapt them.
The screen has up to date charts and tables on it so if you are too lazy to make your own (like me) then its very handy for the updated monster damage, skill DCs and conditions.
High quality printed maps
The not so good:
The screen is kind of thin compared to other dm screens out there but to be fair it was probably due to there not being enough space in the box more than anything. Personally I think they could have made it one panel less and made it thicker (and smaller) as I feel there is a lot of information I just won't use on there, but again, probably a personal preference.
The maps, although very good are only really useful for the adventures in the kit and not very generic. I personally would have preferred a blank wet/dry erase type map like the ones Paizo sell (which I bought anyway) which would have had much more use and longevity.
Magic Items??? I know that the adventurers vaults have stacks of them, but I think it would have been great to have had a better selection (or even a book of them) in the DM's kit, seeing as they are a bit of a Dnd staple, although some would probably disagree with me on this as you can easily make your own.
Overall despite the tagline on the box that says 'everything you need to run a game of Dnd' you can't really. Granted you could run the adventures in the box, but then you'd be stuck, so its a bit daft marketing it like that. I do like the box but its far from being amazing, but I was aware of that when I bought it so I'm happy I have it, it just could have been better.
