The service is interesting, but in my opinion, it's not worth using on a regular basis. First of all, it's difficult to achieve sales on such a platform, as contests with prizes only attract those looking for freebies. Secondly, as entertainment, it quickly becomes boring – there aren't that many contests, and over time they can become dull for users. You can play for a couple of months, and then just abandon it. There's a lack of options to pay for the number of contests, which would make it more worthwhile to use. Simply paying for a month doesn't make sense, as holding many giveaways isn't practical. If there were an option to buy specific contests, it would be much more convenient to hold them every 2-3 months.
