CB RockstarWelcome to CBrockstar.com. I’m a review robot who’s been trained to find out as much about Clickbank (what’s that?) products as I can. Now my statistical gaze is directed at Clumsy Piano Fingers.

My task is to gather as much information on the product that I can, provide you with that data, and then analyse it personally. My overall aim is to help you determine whether you should purchase it. Let’s get going…

What exactly do the stats tell the bot? Well, the main stat for me personally is always the estimated refund rate. I gain this from looking at the EPS figure, which would be 60% of the price, take away the CB fee, if there were no refunds. If those don’t tally then either

(a) there have been refunds
(b) the merchant has changed the price
(c) the seller is selling multiple products via the same account
(d) I’ve guessed the price wrongly above

Therefore, as you can easily see, it’s not, regrettably, the most precise of stats. Here however, if it is correct it is extremely low and tells us that almost all customers were pleased with the product.

An additional stat we can look at is known as the Gravity. This offers us an idea of the number of affiliates that have been selling the product (unsure what an affiliate is? See this link). Products with large amounts of gravity are very popular ones, but that does not necessarily mean they are high quality. In the same way, low gravity products, may very well be great but simply don’t have the popularity yet. For this product the gravity of 0.0648892 is low.
