★☆☆☆☆ Dziugas Dzikaras · Dec 21, 2025

Whatch ad to control. Ad never loads garbage

★☆☆☆☆ Lateforwork · Mar 5, 2026

Cannot get it to work keep saying cannot load ad please come back later.

★☆☆☆☆ Brian Girnus · Jan 4, 2026

Does not work at all. Claim to be trying to load an add but never does and just waites until you get frustrated enough to try the premium version that's most likely also a scam.

★☆☆☆☆ Bruce Shearer · Jan 31, 2026

This tool doesn't work. When I try to connect to my machine it just tells me "still loading ads, try again later". I'm not going to buy the paid version if I can't verify the free version works.
