“Took my MacBook Pro to Jumpplus only to have them tell me my computer required a $900 repair. Would not pay that so I checked around until I found JTG systems. Very honest and helpful people. Had my laptop fixed and useable within an hour. It was amazing how a $900 repair turned into a $60 one. Thanks again to John and the guys. Definately would recommend and will be going back!”
In 99% of screen and battery repairs, your data remains perfectly safe. However, we always recommend a backup before any repair.
Most iPhone screen repairs take about 30-45 minutes. Samsung repairs can take 1-2 hours depending on the model.
