for a picture comparison of my Soggy Mod+ TM-15 with my TM-7.
They are releasing the new V2 Solenoid today, it's basically an adapter that allows you to use the Mini Solenoid instead of the TM Solenoid. The Mini Solenoid has been around for a while and seems like its bulletproof in comparison to the TM Solenoid. I've also heard that a lot of new TM's are coming with the Copper Piston already installed .. a lot of people have had more luck with that than the silver one. Stock lube is definitely crap but even running clean I have startup issues if I've left the marker unused for a few weeks. It usually sorts itself out quickly but it's still annoying.
My single experience with customer service was very good. Not been happy about their sales communication in general though .. the RipClip took ages to come out without a good reason and the new V2 Solenoid appeared from nowhere.
Even with these issues though, I love my TM's and wouldn't change them.
