First time poster long time lurker. FYI as a beginner to this silly game about 3 years ago Your site has helped me more to improve my game than any other.
Just passing along my experience with simulator products. I have had an optishot for two years and just recently purchased a sky trak.
While the price of this is attractive, it is doubtful the product will be a realistic simulator (everyone's criteria will vary). I would guess it at best it would be on the par with optishot, which at just a lightly higher price point is a fairly mature system despite its shortcomings. If you read up on simulator products currently available the club based measurement systems (like this one) are limited in their ability to detect parameters needed to depict an accurate ball flight. Ball flight measurement systems are head n shoulder more realistic.
Given all that, if you don't have room for a hitting net or height to hit a full club the short stick availability could be fun for that situation. I also think another major simulator company is introducing a very similar system but not at Kickstarter prices
just throwing this out there based on my simulator experience for contemplation. Wanted to maybe contribute a little to the site as my real golf knowledge is vastly inferior to the people here, from which I have gained considerable insight
