I've read a couple and decided not to vote on them yet, since voting is permanent yet variable...
Just remember that when you're writing a review, you're not trying to sell the product. The point of the review is to be a truthful and thorough as possible to let the buyer make an informed decision.
With that in mind, have another go through your reviews and see if you can tweek here and there.
just my 2 cents.
They are good otherwise
