This is by far the best product, furniture wise, I've purchased on Amazon! I was skeptical after reading some of the reviews and then really nervous about putting it together because I thought things wouldn't line up.After looking at the instructions and seeing how even a child could put it together, with detailed diagrams that were very straight forward. Pieces are well marked and the instruction manual even shows you the screws you need, at the bottom of each page, for what you're working on. The kit included a nice Philips screwdriver instead of those common hex screws that take forever and 2 glue tubes to secure the dowels. The kit also included 1 extra from each screw, fastener and dowel. It used a dowel plus a cam lock which fit in the slots perfectly!The only caution i would suggest is being careful not to leave much of the wood dowels extending. The should be put into the hole about 3/4 of the way with the glue. One of the dowels i had left too much out and when i put it together there was resistance so i thought it was because the hole wasn't fitting so i tapped it into place but it poked a hole in the panel! I was glad it was black and was an easy fix with some wood filler and black paint! You can see the booboo in one of the pictures. They didn't explain how far to insert the dowel or if they did, I didn't notice. You have to remember to put glue on the extending part of the dowel when putting the pieces together so it will secure on the other side also. There were 5 rubber 3M guards in the kit but the manual didn't mention where they went. I am assuming it's for the corners of the table but I didn't use them. The last picture shows those.The table top also leaves stains from oils in your hands. My hands were not oily but still left finger prints on the mat finish as you can see in the video.The extension parts are very sturdy, I pushed on them several times while extended and they didn't wobble or move. The smaller extension tended to snap back so you have to hold it until it closes. I wouldn't recommend having anything spillable on it when you attempt to close it. Opening it is ok if you have a good grip on it. The larger extension has to be opened and closed holding the center or it's difficult, it has a smoother movement so drinks probably wouldn't be affected too much.The whole table was perfectly aligned although the smaller extension part did not sit flat at first so it looks slightly off in the video and pictures but after a few uses, it flattened good.The larger extension can be mounted on either side of the table and I had to play with it for a while before it aligned right because there were a lot of holes it could go on. The smaller extension can only go on one side.The drawers worked perfectly and well aligned.It took 3 to 4 hrs to put together only because of the playing I did with the larger extension part. I started using the included screwdriver but when i got 3/4 of the way through I switched to a low setting of an electric screw driver. It worked like a charm. My palm had a blister , that's how many screws it had!I priced these tables at over $400- $600 at furniture stores at discounts! And they only had one extending surface. This one has 2! They were also very flimsy and with no drawers.I would HIGHLY recommend this product!
