The assembly only took a few minutes and they were ready to be used with pre-charged batteries. The battery life is much longer than expected and is more than enough for a few hours of use in the evening and should last even longer. The flame looks very real and gives a nice ambience even for my not so elaborately decorated backyard.
I also noticed they are 100% waterproof. There was a big storm and one of the torch lights was knocked down to the ground and the water was everywhere but there was no damage at all.
The lights are very compact and portable so easy to take along with your trip.
I am very satisfied with the product and the seller.
