We have been needing a snack tray for awhile, but I do not like how floppy the Wonderfold one is and I’m not a fan of the 3D printed ones. This one doesn’t have a lot of reviews, but the price is not bad, so I gave it a try. It is definitely worth the money and I would recommend it over the Wonderfold branded one.We mostly use the kids Contigo water bottles. Both the 12oz and 14oz bottles fit great. There’s even a little wiggle room for a bigger cup. I like the deep cup holders, so the cups aren’t constantly falling over. I did see a bad review about the cup holders being in the way and being kicked by the kids. We have the W4 and only two kids, so we haven’t had any issues with kids kicking the cup holders. I could see it being an issue if there were four kids in the wagon… I would say one option could be to buy two trays and try the bus style setup if that is an issue. (I will probably end up trying that soon because my 1 year old keeps touching my 3 year olds seat with his foot “on purpose”. ?)The tray itself is sturdy and the sides are not floppy like the Wonderfold one. The clips look just like the Wonderfold ones, but are thinner and more bendy. They still seem to be well made. The bottom part is removable and has a leather like material that should be easy to clean. The rest of the tray looks like it could be easily spot cleaned or gently scrubbed in the sink if needed.
