I sent in 400 slides from when my parents were newly weds in Germany in the 70s. (a Christmas present for my mom) Needless to say, these slides carry a LOT of sentimental value for me, but I felt like they were in safe and caring hands at digmypics.
The customer service was excellent, with regular updates on the process and prompt correspondence. I had a blast looking over all of the slides in progress, which are uploaded live. The colors all came out beautifully in the finished copies (while still retaining the vintage authenticity of the images).
All in all, a seamless experience (and both my parents are ecstatic to have them!!) and perfect product.
