Query: Good budget wireless bike computer

I bought this computer because it is wireless and you can see MPH, odometer and time all at the same time. The wireless works well. I question the accuracy of the computer. It seems off at high speeds. Also, the readout has a 3-4 second delay. So when you change speeds, the computer takes a few seconds to update the display. My wired cateye does not seem to have this problem. For a serious competitor, I think you would want to spend a little more. But for recreational biking it works fine.
