[EX Q]: NOT VELCRO. Velcro is a trademarked name. This product is regular hook and loop and is cheap... it doesn't grip nearly as well as real Velcro. do not be misled by Merchants who advertised falsely and Amazon's inability to properly monitor.
[EX A]: negative

[EX Q]: I bought this to test it out since I needed to buy several solar lights. The detachable solar panel was a huge plus. I left this out sitting along with another unit from a separate company for a few months I got busy/forgot these were out there. Well I went out today to install it and this unit is dead. I popped the battery compartment no seal in the lid. one of the batteries corroded. So Im going to see if I can bring it back to life with a little cleaning. for now 1 star because it died after a few months of rain.
[EX A]: negative

[EX Q]: Very ingenious, affordable product. It allows us to buy better quality wines without risking waste if we choose to have a single glass on a daily basis. The Preserver seems to be working as advertised.
[EX A]:
positive
