He is a very busy man and this is telling...people know that he is the man!

Took my vintage reel to reel in. Quoted me to replace belt and do some cleaning. Got it home and…read morestill with same issue. Discussed over the phone, took it back, he had it for some time and at one point told me it was too much for him and he is not a reel to reel expert. Well then why wouldn't you tell me this in the beginning? lol Took it to another shop down in the springs highly regarded for reel to reel repairs. They looked at it, seen parts that were supposed to be replaced by Dan in fact were not and appeared used. Called Dan, he decided to berate me like another neg review on here, then decided to harass me by calling me every day for a few weeks to berate me. I had to block him, he still left messages. And he still kept my money despite my doing any work and then using used parts. Horrible business and lesson learned.

The owner Michael (20+ yrs in business) is an honest, old fashioned repairman with whom we felt…read morevery comfortable bringing our three year year-old television for assessment. For a low flat rate, he will give an estimate and apply that service fee toward the repair. If he can't repair it, he will use the fee to recycle the TV for less than the cost to you to recycle it ($150+). It's now illegal to throw out a tv anyway. A win-win for this frugal gal who hates our throw-away culture!

This a small business near the Greeley mall. It's a small husband and wife operation but he…read moredefinitely knows his stuff. What I really liked was the fact that he gave me a day that my phone would be done and even though he had a lot of phones to work on that day he stayed working past closing time to make sure I got my phone back the same day he said I would. A little later but I appreciated the fact that he stayed working after hours to make sure it was done. The quality of work was excellent and I'm happy with the service and the product. I highly recommend this business.
