Oh there are schemes that want to PAY for reviews. We always return products sent for reviews. On top of that, we make it clear that we don't even guarantee a review will be written. We're happy to take a look at evaluation products, it's what we do. But nothing, absolutely nothing can be expected in return.

I can't tell you how many times firms have told me they'll not send any evaluation units because we didn't promise a review. Like we benefit from them more than they do. :)
