Jobber Financing - Who's Used it, Why, and What was Your Experience?

For a few years now I've been seeing this block on Jobber about financing. I have had to pull out a line of credit before a few years ago but thankfully our jobs are low cost enough and cash flow has been good so I haven't needed it again. I'm wondering if anyone has used it, and what your experience was like?

Also, if you've had to pull out a loan like that, what is your strategy for paying it back quickly?
