Pure competence. They know electronics and how to get them working right and looking great. Not always cheap, not always fast, but they get the job done correctly, every time. My dad and I have sent lots of high-end items through Interwest, and wouldn't trust this equipment to anyone else. They always do a great job and they won't cut corners on you. If you want it done cheap and fast, these might not be your guys (though my last order was done sooner than I expected) -- but don't you dare subject your nice equipment to service anywhere else. These guys are the only game in town that can really keep your electronics basking in their current (or former) glory.
Should of read some of the previous reviews that were written about this place before hand. The funny thing is their "known" for their work. So why couldn't they perform? This place is a place full of lies. And the demeanor of the guy that runs this place is laughable. Charging outrageous prices for work that was not even completed. I would never recommend this place, nor would it seem those whom had a run in with this place based off their Google reviews.
The only folks in Utah that I'd trust with my gear. If you have any broken electronics, these guys can repair them. If you have any old electronics, these guys can make them better. They work wonders on high end stereo equipment (which is how I found them). They are serious professionals and they take pride in their work. I couldn't recommend them more highly.
