I forgot to look at the price, but this looks like one of those things you buy, use a couple of times & just go back to the regular way. if you want to cut with 24" connected lengthwise--where would you lay it to cut that far? and would your arm reach safely? it's easy to line up a long ruler & short one to do something like 15",etc. I can see where sometimes I might use 2 or the 24" rulers,(for width) but you can easily line them up if you just take your time. put the money in a couple more rulers.
