You're welcome. I did a bit of work looking into automation in warehouses back then and while we are on the cusp we aren't entirely there for everything. (Quite a few situations do ROI out now and it will only get better.) My notes on these guys was that if you are still looking to ROI out on your existing fleet of MHE in a standard warehouse space it's not a bad option. If you are planning automation from the start though there are better options.
