Yes. It is great. First thing in the morning it takes a couple of minutes to lock into the satellites, but after that it is almost instant. I have mine displaying mph, No of satellites and altitude. I only use it for mph, but the mph display, on its own, looks rather insignificant as the blur swirl isn't there. It only shows the battery voltage if you supply it using the supplied plug for cigar socket. I use mine plugged into a USB supply, so it only shows the 5V of the regulated supply.
