I wish you luck but I do have concerns regarding the posts you may get. You are seeking honest reviews but what is an honest, unbiased review? If a review comes out as totally in favour of a product and gives glowing reports, does that make it honest or biased? If a review comes out with 'warts and all' comments then does that make it 'honest' and all encompassing of the true propereties of the product? Add to that the natural propensity for reviewers to post negative reviews listing faults with their review sample rather than people posting a glowing review for their own purchase and you can end up with a biased impression. The end result is that I think more people are likely to post negative views rather than positive ones ... just human nature.

I am not suggesting you are not providing a valuable service ... you are and I would certainly read what people think. But I expect more negative reviews that positive ones; and accept that this is not necessarily a true reflection of the product under review. The review will show what 'might happen' not what will always be the case.
So ... good for you and well done.
Cheers, Phil
