I use Getwinner to organize giveaways on Instagram. It's very convenient and simple, the setup takes little time, and there are no difficulties with selecting winners. What I like: 1. Automatic winner selection according to the contest rules. 2. The ability to customize various types of giveaways. 3. It works quickly and without glitches. 4. Affordable price. The service really saves time and eliminates the headache of counting participants.
