I like it for market data. It's mainly supposed to be a marketplace for graded trading cards, but doesn't seem a lot of people use it to post their cards. They're some, but more people using it would quickly improve that. It's best for looking up a specific card or player for market data. It tracks sales across platforms like ebay, myslabs, and several auction houses and gives you an average value based on card grade. Also, it shows each cards graded population across psa and beckett.

Doesn't show market price of listings, doesn't count in shipping price (or destination eligibility!), poor filtering (not even by language), no long-term price graph, and extremely slow to navigate with no concept of "caching data"

Sent in a bunch of cards they valued at 1050 approx (collectr value 1250), ended up selling at auction for barely 800, better off using Ebay or selling it yourself elsewhere. Otherwise be prepared to take huge loss of potentially > 35%. None of the cards even reached the average of their estimated value on the app, they told me they had a lot of users but even low population rare PSA10s couldn't hit the middle range.
