Yes, I have had it for about 3 years. It is very good! It is also designed for anyone to use, you don’t need a PHD to find it useful. The translation is very faithful, and it has a fairly good critical apparatus that will give you the variants to the MT and the Septuagint as well as other DSS manuscripts. The only downfall that I find with the book is that it does not provide headings at the top of the pages for each page to let you know what book of the Bible you are in, so you need to go to the table of contents to find the page number for what book of the Bible you are searching for.
The introduction is very informative about the DSS. This is one of the best bargains out there! You can find it on Amazon fairly cheap, $8.99 used.
As far as being professional, it is very much so. Two DSS scholars (Abegg and Ulrich) that I am very familar with are 2 of the 3 that put it together. They have done much for the scholarship of the DSS.
