I too took advantage of the $15 Groupon for my iPhone 3GS. The staff was very friendly, and did a perfect job repairing my cracked glass. My Groupon wasn't valid until the following day, and they were kind enough to honor it a day too soon- much appreciated! They do take their time to get it right. So, don't expect a 5 minute job, but do expect to be pleased! I would absolutely recommend their service to friends or family! Thanks a bunch Desert Wireless!
