Retrieval speed is very fast. Superior to other chalk lines. Is a little bulky. Chalk and this unit are a little pricey, but worth it. Review: Great. - Takes awhile to get chalk in the line good but once it’s worn in a little bit it’s fantastic. Gone through so many different kinds. Hope this one holds up for awhile. Also a this one in particular seems to be a great little plumb bob if needed. ## Features - ULTRA-THIN SNAP LINE - 0.5 mm braided nylon line produces clean, clear, accurate snaps for the precise finish carpentry work.
