Is Angi Worth It For Home Service Business Owners?

So i've tried using both Angi's and I legitimately feel like it's a scam. That being said, I talked to a guy in a different market last week and he's killing it on Angi. I told him thumbtack was amazing and he thought it was a scam. I think when you are starting out you have to try all the major lead sources then see what works. What I don't like about Angi is they lock you in to a contract so I would try to avoid any lead source that forces you to contract.
