BigTone Trem Vintage Orange : Too good to be true

At first I didn't like the tone. But thereafter I started to like it and now it's like a benchmark for my other guitars. I put 12's strings, because it's Jazz guitar, it has to have 12's and now sounds even better. Unfortunately with 12's strings it's not possible to have good intonation and use the additional tension bar on the bridge, so I bypassed it and everythings looks and feels OK. During the period I have it (more than 6 months) I had two issues - the volume pot for the two pickups unscrewed and I had to screw it back, the other is that two times the input jack inscrewed. However it's not a big deal, because I mainly use it at home and have the tools, but it quite questions me wether I need to carry tools with me if I use it outside more often.
