Is it worth it to buy a standing desk/desk with adjustable height?

I just got the Omnidesk Zero Electric. It helps with my back pain, but I'm still unsure if it is worth the price (quite expensive). I do regret getting the accessories (cable management bar and mounted powerbar). You can get the same products elsewhere at a lower price.

Subjective, to me not worth it. Rather buy secret lab chair if have to spend such an amount
