I’ve gone to the tech shack before to simply check out the place and enjoyed the very welcoming feel of it and (of course) the owner who is absolutely laid-back, knowledgeable, and charismatic. I tried replacing my battery with one that was non-OEM and he warned me about any issues that I might run into. I couldn’t replace the battery myself and he was able to put in the new one with ease (even though it didn’t fit correctly). The price was $35. I didn’t feel like I was overcharged because he not only did the replacing for me, but gave me warnings and what to look for in the future when it comes to tech replacement
