I have one from your first link. I got it on sale at JoAnn's. The other comments are right in that it is not the most stable table I have ever used but it is serviceable. I like the height. I'm 5'2" and it is the right height for me for cutting and standing to do anything else. I also like that it folds down to a narrow profile and you can have just one side up or both.
When I set up my sewing room in my winter home I didn't go with that table however. I got a table at Sam's that is adjustable height and folds in the middle for storage. I like this one because it is more stable and at the highest height is is good for cutting. I also have 4 pieces of 2x6 (2 for each side) that fit under the legs if I want it higher. This gives me a lot of flexibility with different heights given the table has 3 options and I have another 2 with the 2x6 boards. I use it at a lower setting and put my sewing machine on it when I am quilting as I need a large space to support the quilt. When it is not in use I can easily take it down and folded it is a very narrow profile that fits under a bed etc. This was also a lot less expensive. I think it was around $40 range.
