The most important thing I like about harbor cloud, it's price point compared to other providers in this market space! Their support team has been very helpful as well!! Nothing much at all but they are great folks who have helped me out when needed over email or phone calls throughout my experience using their products/services here so far - nothing negative that comes up while working through them thusfar either though :).
We've used several VDI vendors now for various projects we're doing including work from home employees etc., none of which were able compare favorably against what was offered by harbcloud- pricing wise anyway! They do offer some nice features such as being mobile friendly too if you need those types things along wthe rest :) Would highly recommend giving these guys' service another try especially since your looking into getting services where cost can be prohibitively high ;)!
