Works great for my application.
Size: 6Ft-without USB
This power strip saved me a lot of trouble. I used it to power my Its a Wonderful Life Village, which is composed of 22 buildings each with its own lamp. I went from four power strips to one with this unit. It made the wiring so much neater.

A must have power strip!!!!!! Highly recommend.
Size: 6Ft-without USB
I purchased this during Prime Days in July for $18. There were multiple reasons I purchased this power strip. The list is as follows: The plug is flat to the electrical socket The plug rotates, which makes it so easy to plug into any socket and there have been many times I could not use a power strip because of the socket availabilty. There are sooo many places to plug in anything and they are far enough apart that you can use smart plugs with ease. The cord I purchased had a 6 foot cord, plenty of room to place the strip behind anything and have room to get easy access. This strip is at 4,000 Joules, which is very good surge protection. For the price point, even if it is not on sale, would be worth the purchase. This is a must have in this day and age of power needing devices. P.S. I would have purchased a Amazon strip, but they were “not available” during the Prime days sale.
