Purchased one of these when they were $40. I liked it and thought it was pretty cool, so purchased another 2 when it went on clearance for $30. I think the price is worth it at the original price tag so this deal is great! Pretty cool effects. I highly recommend them if you are into lighting. Also FYI, these may be smaller than what you are expecting.
