A note regarding reviews: Product reviews on this site are the result of me buying the reviewed equipment off the shelf or online. In the event that a vendor has provided a free sample for review, that fact will be plainly stated in the review and the vendor will be informed that I will post my true feelings, whatever they may be. Come to think of it, that may be why I don’t get many free items from vendors to review.
