Folks, Not enough feedback on JonSnow as a vendor, so here's my impression. I have purchased several products from him over the last couple of years. The products work as expected, and when they don't, communication with him to resolve issues via Telegram is good, until it is decided if it was my issue or his. I use his products on more than one pc for a single unit price, and an satisfied with the products and service. I like that his catalogue of products lists prices and versions provided. If no version is listed, He will respond to your query with the version He has available.
He does provide updates at no charge, although He may not always make you aware that there are updates available.
Anyway, thats my two cents worth.
