Couple of days ago I purchased UBot 5, my first UBot, and have many have noticed it has a few things that need to be fixed. So I emailed customer service and they were very cool, let me download and run V4 until the bugs are worked out on 5... This company is doing great so far in my book... Now I can jump into learning UBot and then when 5 is working better, Bammm, blast into the newest stuff ready to role... Thanks to the folks at UBot Studio for being cool about it all.
