I have had 3 of this same model down through the years and keep coming back. These are a basic, reliable unit that will give you speed, average speed, keep trip miles and overall miles. It doesn't do cadence, heart rate, etc. It adjusts easily to wheel size to be accurate. Typical battery life on a 2032 (sensor and computer) is about 6 months to a year of reasonable use. I have used them in rain with no problem. It comes with everything you need to install it in about 5 minutes. You can't go wrong on this one for the price.
