The product seems sturdy, but it is not 3x6. It is 3.5’x6.5’. I bought a true 3x6 flood table tray and it was not big enough for the tray stand. Returning and just using a 6x3 folding table instead.Good system but I needed tools to put it together because my box was dropped on end. This bent one end of every side rail and end rail. I was able to mallet it together except for the part in the picture. Pliers were use to get the kink out enough to finish assembly with the help of my mallet.I purchased the 3x6 stand, it went together very easily. The support bars that hold the tray are not fasten down, they slide into position, but they also can slide out of position. I did not order a tray, read the reviews.I personally think you could purchase a few sturdy saw horses and a piece of ply wood and make a table that holds your tray.I purchased an affordable 3x6 tray at my local shop. It doesn’t fit perfectly ( little small all around ) but it works.Basically it’s ok,but once again, I think you could build one yourself at a less expensive cost.This was the easiest stand to put together, no tools needed and it all fit just right. I just wish Amazon didn't charge so muchthe tray is strong and goes together pretty fast. they didnt clean out the metal shavings in the square tubing before welding them closed so you will probably hear stuff bouncing around in there. if your is like mine you will hear quite a bit of stuff rattling around in there lol.it would have been nice to have screw holes or something to secure everything together. while its sturdy when it sits if u want to tilt it slightly on 1 side to drain water to clean the res tank u will quickly find out that the legs will pop out and one side will come off of the table leaving you to scrable 1 handed to getit back in place without dropping the tray with your plants in it. a way to secure the pieces would resolve this 100%.I have nothing to complain about. The product is strong, well built, and can be disassembled and reassembled hundreds of times.This is a perfect tray stand!I have the active aqua 4x8 ID and they fit right in there with a little extra spaceFácil de armar muy prácticaI picked one of these up for $88 without realizing the regular price. Wow that's expensive! However, at the sale price it is a great buy. There are no locking parts, everything is held together by gravity, but it's very heavy duty and sturdy. It goes together in about a minute. It has been excellent for me so far.
