It's been a little over a year since Techna Glass replaced my back window's tint and I'm still very pleased with the result.
My used '07 Hyundai Elantra had a HORRIBLE tint job when I bought it. Techna Glass was referred to me by a friend and I was able to set up an appointment that same day. They quoted me a fair price and I was even able to save $25 by using the coupon on their website. Easy as cake!
The only complaint is that when I showed up to the appointment I made over the phone, they were super confused because my name wasn't on the books. Not for that day, not for the day before, not even for any day in the future... It was bizarre. Thankfully, they were able to squeeze me in. Overall, it took less than an hour and I was on my way once again. I'm very happy with the service and I'll definitely be back to fix the rest of the windows.
