very easy to assemble, online manual and assembly instructions. I really enjoyed assembling the kit, it’s the second I’ve bought. arrived safely and well packaged and I didn’t need to contact the seller.

This is a really good kit and the result is a very adjustable product, much better than XR2206 kit which is a poor signal generator. My only wish is for part values to be printed on the PCB. They provide a QR code to go in and get a ZIP file which has CN and EN manual, schematic, etc. I built this in about 2 hours start to finish, the parts were perfectly supplied. Adjustable duty cycle, frequency, offset, amplitude. Two smaller potentiometers allow you to fine tune the rise and fall of the signal cycle. Yeah the baggie package results in bent IC leads but can be easily restored straight. All you need to provide is a 12V +TIP power supply with larger coax connector, you might have an old router adapter that will work. I love kit builds and this one is at the top.

This kit is of very good quality. No difficulty for mounting. Performance is not extraordinary but more than enough to tester or repair audio devices

The package was apparently lost or stolen, but I got a refund

Happy with the purchase. Fulfills its function perfectly, and with this price, I would buy it again without hesitation.

Capacitor C9 missing when checking against parts list. Should have been 6 x 104 capacitors only one was missing! I did however have 2 x 105 capacitors, but the project only requires 1 x 105, so my guess is a 105 cap found it’s way into the box of 104 caps, right number of caps for the project, just one wrong value! Other than this small hick-up, kit is just fine, almost complete with testing to follow.

Thank you for your feedback! We’re glad the kit is working well overall and appreciate your detailed observation about the capacitors. Happy testing!

Both kits ordered worked without any problems after their completion. Price-performance 1A. Nice craft fun, and a usable little device as a result

A thousand pardons, I have been reviewing and I received the order in November, and of course I get a message on December 5 that I received it and I did not receive anything that day, if you look, I’m buying many things and of course I got involved, I have reviewed the content of what was coming and I have seen that I already had it but from two weeks ago. I am very sorry because I am very happy with you. I ask for your forgiveness or more.
