These pedals are heavily discounted. No idea on the quality - but obviously don't expect a Strymon at this price. Classic Distortion, Incentive Overload, Compression, Vibrato, Faz and Echo available at time of posting. Keerygo Keerygo Store is the actual seller as pointed out by Jong, not GB.
Edit: Some other discounted pedals around $28AUD here https://www.gearbest.com/guitar-parts/pp_009814289982.html
It's not actually Gearbest - they're outsourcing their platform to other stores (in this case "keerygo keerygo Store").
It's kind of like eBay, except there's no way to tell if Keerygo is a scam, or how much stuff they've sold before, or how long they've been a member; and without eBay's strong consumer protection rules.
