It's simple to use, it works with all versions of QB (including Mac) and is free! I wish there were more conversion options available in the software but that seems like an unlikely problem because you can export/convert to any other file type as well. So far so good - it has been very helpful converting old documents to QBO files. We have had no problems using this product. The only downside was having to convert our older records at first. But now we are able to keep them separate and not lose valuable information by doing so. We also realized how much time we saved since we didn't need to spend hours manually entering data. Having everything in one place makes life easier when working between two different programs.
