I use my card virtually every day. It works great and the 2% is easy to earn. The only downside for me was the 3 CRA pulls to get it and of course reporting to personal credit.
Mine started out as a classic and then upgraded all the way to the Green 2% card so I missed out on the SUB. But I would think it would be able to achieve the SUB fairly easily even with a smallish CL. Just might have to pay it off a couple times a month.
We have one of these. We added a Chase Ink this year also. We have a lot of the bonus spending and shop with chase. All the misc goes on Spark
Biz owner here. Never had a business credit card. Looking to get one though. My credit scores in all three bureaus are 682-685. No deliquents at all or judgments, just high debt for student loans (which are all current). All the forums state that Spark Classic is the best, however I'm looking to get the Spark Select. Been in business since 2010 with no negative information on my D&B report.
