It's been several months. I always do a follow up after several weeks or months to determine if changes warrant a review. I also return to the products webpages time and time again to determine if and when they're updated, revised or discontinued, including mergers, acquisitions, etc. I encourage you to do the same and stay abreast of recent developments. Being up to date on each product, it's quality, particular standards and level of practical application is simply due diligence that should be performed routinely.
