I've been using this product for just over a year now. It's very useful in an audio recording situation, and much more reasonably priced than some competing products. Its ability to display a metronome track is a very good and useful feature, as well as changing colour in a pre- or post-roll state. the two slight drawbacks are that to use it with a cable long enough to stretch from Control Room to Studio (i.e. more than about 3m, it needs a USB booster cable. Without it it's unreliable over a longer cable run. Also, if you are using MIDI tracks in your project, do not attempt to edit events with the Punchlight connected. If you do the events re-assign themselves to MIDI note 1 and cannot be moved. Disconnecting the punchlight (or removing its output assignment) stops this. If you want a useful studio light on a budget, and can accept these workarounds, its a good piece of kit.
