This guy is "very" creative and "patient". This is not the only module I bought from him, and I am still planning to buy one more. However, this module in particular contained some bugs, and because I really loved the module I tested every single feature of it. Then I pointed out the bugs for him. So in less than 24 hours, he got them "all" fixed and instantly uploaded the file to the unity. I wish him the best of luck, and I would definitely keep an eye on his upcoming see more modules.
