I am just an electronic hobbyist and don't have a massive budget for buying test equipment. I have needed an inexpensive signal generator for my workbench. When I saw this one on Amazon, I decided to purchase it. I was expecting a cheap "knock-off" but one that would fill my needs as a hobbyist. I was correct in all respects. It was cheat and it was more than likely a "knock-off" of a more expensive unit, but to my surprise and delight it turned out to be a real powerhouse. Functionally I can generate just about any waveform there is, along some of my own making. As near as I can tell, the accuracy is "spot-on" and it has functions that I would only expect to get in a more expensive unit. The Documation is not bad for something coming out of China though its' operation is pretty much intuitive. Great buy.

A great product! Very nice and neat case, small size, is very accurate in its measurements (I have multiple calibrated meters and this one is just as accurate) and has all the functions you need from a multimeter plus the large screen ability makes it very versatile.
Both my colleagues saw me using a multimeter, consulted me about it, they both bought one, and each was very happy with his choice. I recommend it unreservedly.

Comes with a cheap power supply and does not protect itself from the noise leftover
Update: Seller reached out to me the day this review went live and offered to replace the power supply that was bad. Changed the review to four stars as the function generator is good and the product support was great.Overall not a bad function generator for the price. It has worked well for everything I have needed to do with it to this point. The signal does pull down a significant amount with a load but I figure that is to be expected in this price range. Now on to the dinky power supply they provide with it...I kept seeing weird anomalies in the readings on my scope. I suspected the power supply included with the function generator to be the issue so I switched the generator to use my adjustable power supply set to 5v and suddenly the anomalies were gone. Connecting the output of the power supply directly to my scope set to AC coupling produced the picture attached to this review. It is possible that I just got a bad one but it seems unlikely.

I am just a broke college student so this is all I can afford and i think that it will server me well for a years at least but. however I do have a few complaints even though I know this is just a cheapy ill still share my complaints. I haven't spent a lot of time with it yet but my first and only user complaint is that the square wave is very peaky and ripplily. but that's kind of expected for this price if you really can't have those peaks in your circuit pick your voltage ahead of time and use Zener's. then I have a construction complaint. the soldering seems mostly good espillaly on the main board but on the front panel board the rotary encoder and the main power button had a but of flux and gunk on them i dont have photos as I already cleaned it but trust me they were there and if you buy this you may want to do the same. and my biggest complaint, design. why are all the part numbers lasered off? there is no good reason to do it. only reason is that they are lying about the specs of the device and dont want you to find out. but I mean every chip is lasered not just the main one all these op amps and transistors no part numbers, i mean how do I replace the part if it fails? terrible practice and quite sketchy wouldn't stop me from buying it if i had known but I'd be much more happy if this was not the case. also they use self taping screws. no surprise but itd be nice if it had metal threaded inserts.
