The stands' articulated-leg design has both advantages and disadvantages. Each joint can be locked into any of 24 positions, so with three joints in each leg, there are a very, very large number of ways the stands can be employed. However, even though the joints have numbered and tick-marked degree indicators, I still found it difficult to re-create a particular position I liked, as well as to get both sets of legs to the same place. Uncaged could do more to provide simple tools to mark positions to get back to them rapidly, such as color cues or position markers. If I were to use the stands permanently, I'd likely use fingernail polish or a colored permanent marker to indicate my preferred positions. Also, let's not forget about fingers: While Uncaged includes several warnings about pinching, it's simply inevitable that at some point you'll get a finger squeezed when clicking and unclicking the legs--I did. It smarts, but I survived.
The stands are surprisingly light, at 4 pounds for the Executive and 3 pounds for the Professional, and they fold up compactly enough to lug around. In fact, I'm surprised Uncaged doesn't offer a custom carrying bag of some sort, as even though there are no sharp edges, there are rough ones--I wouldn't throw either stand into a bag with a laptop or tablet--and each is too large stick in a backpack.
Despite the solid construction, the company offers only a 30-day warranty against defects and assembly. Although Uncaged Ergonomics is a small company, the 30-day policy for problems not caused by the buyer seems rather restrictive. On the other hand, the company offers replacement legs for $3 each, which indicates it isn't trying to make profits on parts.
Macworld's buying advice
I recommend the individual stands for anyone who regularly needs to set up a good place to work where the available furniture or surfaces are poor options--assuming toting a collapsed stand is worth the effort. But I really like the Executive Standing Desk combo as an inexpensive way to try out the standing-desk experience without purchasing a new desk. Its modular design also means you can move one or both stands and work in a sitting position. It's a workable solution for varying your working position without the customary high price tag.
