Using these will let you know if you like trekking poles enough to invest in adjustable ones with comfortable hand grips. I have to use adjustable poles because the pole length I need for hiking is shorter than the length needed to hold up my shelter! If you're less "vertically challenged" than I am, this won't be a problem.
How much do these poles weigh?
