This device does in fact display the spectrum of RF signals in the frequency domain, not Sure that the term analyzer is appropriate but it is billed as simple and handheld, generally it does work. The UI is a bit odd but once you get the hang of it, works well enough.No way to move a measurement cursor to a particular Displayed signal , which makes it awkward to Center the display onto a desired signal. Others have recommended it would need an RF amp to boost the sensitivity to enable “over the air” signals from an ant and I agree. All in all it does work and might be a relatively inexpensive way to fill a blank spot in a hobbyist test kit. Originally I received a broken device (damaged in shipment). I contacted Bangood and after a bit of discussion regarding pictures of the damage, Bangood did in fact replace the unit. I am actually pleased with the Bangood service. The problem was not created by he vendor but rather by the shipper. I have had several deliveries by DHL and have had issues each time, not to mention receiving a brokerage bill from DHL after they were good enough to break my goods in transit, ( now that is A full Service organization). I have given a very good review on customer service. A mediocre review on logistics mostly due to DHL awful performance, offset by Bangood’s excellent service in resolving the problem of damaged goods caused by DHL.

Received this multimeter on time in good physical condition. Upon initial testing, DC voltage ranges read appox 15% low. This multimeter is either defective or is way out of calibration. Emailed Bangood several times, no response. As of now I recommend do not buy this device and do not buy anything of significant value from the Bangood platform. I will amend this review if the situation is addressed by Bangood.

Bought x2. Both in good condition. Initial testing, both set to 4.8v. Followed tip from utube to perform minor alteration to allow these units to be adjusted for 5v output. Current meter works well and reasonably good regulation. ( 5.2v no load, 4.9v at 2amps). Some high freq noise/ripple a few % but not bad for $20.
