I know that was the case at one time, but it looks like they fixed that? Or at least that's what their reply on that page suggests (I trust their reply more than the picture summit uses).
But I haven't bought that exact sku, so can't say for certain, but the information provided says that's the balancer OP wants. If it's not right, should be easy to send back to summit and let them know Fluidampr is FOS.
