Rated 4 out of 5 by from Fit for the job, with small reservations I chose this product over a thousand other, cheaper alternatives available from certain unnamed online market places for two reasons: 1) It works with USB 3 2) It has the maximum current feature I must say, the first impressions are good. It looks very nice in its clear, transparent case. It worked right away and performed all the functions correctly. There are two things to keep in mind: 1) The measurements are updated about once per second. If you are looking for short current spikes, you may miss some. 2) To measure the maximum current, it needs to be switched to the maximum current mode. Do not expect to monitor the real-time current and rely on the device to keep track of the maximum current, it won't. It can do one or the other. Do I regret buying it? Absolutely not! Would I still choose it over a cheaper alternative if I knew the above beforehand? Definitely! Am I happy with the purchase? You bet! ;)

Rated 5 out of 5 by from Works perfectly Bought this a while ago as the one we had wasn’t the best quality. So very pleased with this USB Power Meter, works perfectly every time. Totally recommended.
