I don't like it. It's very detailed and I thank you for your effort.
However, you could have saved a lot of time by saying: See T-stick plus. Most of your review concerns issues that are the exact same as the t-stick: mounting, installing, switching. None of that stuff has changed.
What has changed is the magnetic system, which you don't touch on enough. Andy has stated that the reason he went to this was that too many people complained about the weight of the t-stick, even after he went with the lighter action microswitches.
So, instead of basically writing a new review for the t-stick design, I would have liked to see you tackle the differences in game play of a t-stick versus a mag-stick, particularly since retroblast did a review already on the t-stick.
The main issue I think most are wondering is what is the possible drawbacks between a magnetic system vs a spring system in terms of playing. There's always a balance between effort required to engage and corresponding stick action. Does the magnetic system return to center fast enough, especially in games that require fast movements like shmups? These are the types of games that work well with the J-stik (sanwa), which happens to be the closest thing in terms of throw weight to the mag-stik.
