It is impossible to really tell the quality of something when you buy online.  The best you can hope for is great reviews and a return policy.  I cook on my BBQ (Green Egg) as many days a week as I can.  My BBQ tools take a beating.  I wanted a new set and better than the average set.  Fire Magic came up as one of the best.  
I like the set, yet I would have given it a 5-star rating if it had a little bit thicker metals.  The investment was fair for the quality still.  I love that I have a bag to store the tools in.  The brush that comes with it is  waste.  Instead, they should substitute a grill top cleaner.  Just my opinion.  You can't go wrong with this product.
