Very sluggish. Press on a key (button) and it acts like it is locked up, but it's just being stupidly slow to respond. Pops up with erroneous trucks to log into after you've logged out of them. I wouldn't recommend this software. It was bad before the February update now it's even worse. Trying to connect to Bluetooth is always an adventure in the morning. I hate this software but I'm forced to use it.
