Like most fellow reviewers I had a great experience recently at this place. I had the screen of my iPhone 5 bulging out. The gentleman was very friendly, explained clearly to me what the problem is and himself suggested that he would replace the battery, fix the screen back and see if it resolves the problem (unlike all the other places I have been to - who said i need to replace both my battery and screen). 15 mins later my phone was almost as good as new. They are cheaper than all other nearby stores, accepts credit card (unlike some places), provides warranty for their work and are very customer friendly.
I hope I do not have to go to a repair shop soon; but if I do have an accident with my phones, laptops or tabs - Sun Cellular is the first place I will visit.
