Great product. Assembly was supposed to involve pushing the screws in hard enough to create their own holes. After 30 fruitless minutes, we used a power drill to drill very small holes and then insert the screws.after that, assembly took 5 minutes. 
We filled the entire table with a total of about 45 lb of sand and my child mixes in a few cups of water before each play session. This makes for great sand castles! My only suggestion is to make a cap or plug to put in the umbrella hole when the umbrella is not in use. Lots of sand gets lost without it so we’ve had to put a bucket under the hole to catch it. It seems sturdy and has an excellent lid. It’s a perfect height for our 3 year old (will probably remain a great height until she’s 6 or 7). There’s lots of space for mom and dad to play with her as well.
