I use DT25 in my green flanker projectors that I do shows with. They have always performed very well and I have not the slightest complaint on them - absolutely unbeatable for the money. They combined the quality of DT with some fine electronics expertise and I would sell them again without hesitation should the opportunity ever arise.
Incidentally I have never had a problem with any of the DT scanners being returned as faulty - they are a credit to Jian!
