Disclosure: I get a small percentage of your purchase if you use that link to buy the scan tool.
I've had it since April, and I love it. It has a clear, simple readout I can see in daylight or no light because it's back-lit. It runs off the ODB port, so no batteries are required. It's small and light, and it works on my '97 850 as well as my 2004 V70 R. And yes, it turns off the Check Engine light in both cars. In other words, it clears codes.
It's got only two buttons so it's idiot proof. Even though I do web development (light programming), I crave simplicity. This has it.
