Keep in mind, they are looking for honest feedback on the products and not the excitement of new equipment. Not saying that's what your plan is, but good or bad they want it.
That's why I not only shared my thoughts on them, but I also filmed other randoms and/or playing partners as well. I wouldn't tell them what or how just I needed content on a piece of equipment and then handed them the club without knowing what it was essentially. I actually enjoyed that the most and had a lot of fun with it.
I like the post and will take it to heart in my reviews... I also will encourage the "blind" test.
