Very good product. Date: Apr 28 2026
Summary: Excellent.
Nothing has ever gone wrong for me with this tool.
It's done exactly as I've wanted it to as a crypto trading hobbyist.
If I scaled up my business endeavours to professional trading, I would still use this tool. It's that reliable.
I'd just need to upgrade my yearly subscription and it would be "plug and play" so to speak.Positive: Everything feels modular and interconnected.
There is a high-quality customer support bot and human assistance where it's needed.
The calculations are accurate and the tool corrects errors that I had no clue about.
I completely trust this tool because it's earned it, through good results and quality, especially for the price.
This tool has a massive range of support and integrates well with other tools like TurboTax!Negative: I noticed that one article, specifically about importing into TurboTax, was not kept up-to-date and so I had to figure out a big problem myself when the article could've took hours off of my workload.

I found the same with overly optimistic sync time estimates.
The tool read that sync could take as long as 5 minutes.
It took probably about an hour or longer for a few accounts, presumably because the service is very busy during the end of tax season.
I spent a long time troubleshooting but if I knew that it would just take more time, that would have cut down a lot of my workload.
But, because of the excessively optimistic time estimate, I thought there was a bug and wasted twice or three times the amount being stumped and getting frustrated on what's going wrong. -
