What merchants praise

“Great customer support. Actually AMAZING customer support. I was unable to get a validation tuned to effectively block a BOT attack. Customer support tech Andrea set up an online call where we worked through the process to arrive at solution. He spent the time to get it right and then stay on the line to test the validation to ensure that it worked correctly. Five stars isn't high enough for this kind of support.”

What merchants complain about

“Free plan says "Free for dev stores" but I cannot add any validation rule without subscribing to a premium plan. Cannot properly test the app thus cannot install it on my client's store with confidence.”
