Review on Improve Your Golf Game With PlayBetter Swing Caddie SC300I Launch Monitor - Choose From Accessories Bundles For Accurate Distance, Smash Factor And Ball Speed Readings by Chris Nonamaker

This is a sub $500 launch monitor, so proper expectations are needed. But within 15 minutes I had it open, adjusted my club lofts, and was hitting into my practice net. The included case is nice. Unsure why it has a powerpack as it runs off Triple AAA and not USB power.Other sites have said it should be accurate within 2-3%. I'd believe that. It won't be perfect and it probably misjudges some stuff since it doesn't account for curvature or other factors, but if you want some form of reliable feedback for backyard practice, this is a good option without going up in price significantly.
