Avoid at all costs! Do not use them, use one of their competitors. Any of their competitors, frankly. From the get-go, everything took forever to on-board. It took them two months to set up my account, even after badgering them about it (daily) for a month, via chat. In the 6 months that I used them, they removed but a single negative remark off of my credit. 1 out of the 20 (across the three major credit bureaus). Terrible execution on their part, from their membership correspondence to their ambiguously phrased chat responses. "We're sorry, we really are..." or "Bear with us, we are trying hard for you...: Blah, blah, blah, blah, blah... They removed ONE SINGLE NEGATIVE REMARK IN 6 MONTHS!!! I spent over $1K using them and they did virtually nothing for me. Save your money and go elsewhere or call the credit bureaus yourself, as ALL THEY DO is challenge negative remarks. Their service is pointless and costly. I'm absolutely positive you'll get some bureaucratic, bull crap answer from them below my review, but know this. THEY DON'T DO THEIR JOB AND THEY MAKE UP EXCUSES and their software barely functions. I complained to their IT department 10+ times and they still didn't fix it on the 6th month of service. Just rubbish!
Credit scoring models usually take into account how much you owe compared to how much credit you have available, called your credit utilization rate or your balance-to-limit ratio. Basically it's the sum of all of your revolving debt (such as your credit card balances) divided by the total credit that is available to you (or the total of all your credit limits).
