Let me give my opinion. H&H was not my main lab for the first 7 years. I would occasionally use them for something my lab did not offer. I sell a fairly high priced album to nearly every senior that walks in my door, so I need one that looks and has a tactile feel of something worth investing in. 2 years ago I was looking for a new album as an alternative and chose H&H's photo cover. It quickly became my best seller even though I had it priced as the premium choice (which actually cost me less to purchase). I dropped the previous album and added their metal cover as the new premium upgrade.
I was still using the lab I had started with until this summer. I had a customer service issue with them (nothing huge) and on a whim decided to place the order with H&H. To put it lightly, I was very surprised at the difference in what I received. First, their packaging was so nice that I could give it straight to the client if I did not have custom packaging. Everything is protected better than any other lab I have ordered things from. Their colors had much more pop to them on the images ( I do not have labs adjust my colors). Just to make sure I was really seeing what I thought, I ordered a couple of the same prints from my current lab and compared them side by side. The proof was obvious. Needless to say, all my prints, albums and cards are now ordered from H&H.
