I'm being prudent in giving it 4 stars since I just got my phone fixed yesterday. Will wait 6+ months to give it that additional star if it deserves.
Problem: My headphones' audio jack connector snapped with the connector still inside my phone. I tried to fix it by watching DIY videos on YouTube and applied glue and ultimately made a mess for the worse. (Phone model: Samsung Galaxy S4)
I came across the micro-techno website and gave them a shot. Jeremy was the one who fixed it by replacing the audio-jack completely. I was charged around $25 for the service and around $15 for the parts. Seems reasonable since it works fine now.
Reason for 4 stars - He did it in 10 minutes!!!! Flawless replacement.
Hope I don't have a reason to visit this place again but will be reassured if I do allow myself to be clumsy again! :)
