Here is a review with some comparison between the two models They got a bit more throw out of the PRO model, but some say at the expense of beam quality. There is another thread where the models are discussed… still looking for it.
Lots of back and forth on the two models…
BTW, I saw that Wurkkos still has the original Ts30S for sale $69… So if you are real curious, I suppose you can get both.
I have the PRO and like it. It does have Andruil 2. I think the previous version was Andruil 1 (IIRC) . If that makes a difference.
