I tried Experian Boost, against the advice of people in this forum. They were correct, but for other reasons. Boost will give you a bump if you are trying to increase your credit score from damaged credit. HOWEVER....
This only applies to Experian. And there is a dark downside. I allowed Boost to capture my bills including Netflix. And me, being me, am constantly losing my credit cards, leaving them at a bar or restaurant and forgetting to close them, and just being forgetful. This means I have to re-order the card, change the number in my auto-deducts, update my Amazon Prime, etc etc.
Experian boost requires you to go in and change or update your credit card to capture payments. I had several "pending" and am unsure if my score would have been hurt by leaving them in pending status rather than update the credit card number to show payments. This unknown factor is Risk #1. If and when Boost will penalize you if you fail to make payments is an unknown.
But that is not the worst. I decide to dump Netflix. In doing so, I lost 5 (FIVE) points immediately on Experian just because I no longer wanted Netflix. This is Risk #2.
Think carefully before doing Experian Boost. For any upsides, you risk losing FICO points unexpectedly or when you decide to cancel a service like Netflix. It traps you into your currently existing payment structure. I do not like unknowns, particularly as I am going through a mortgage prequalification. Risk is not good, and Experian Boost is risky up to (in my case) 5 full FICO points.
In my humble opinion.
