I have several things from them. They tend to be well made, especially considering the price. I have the transistor tester, the LCR tweezer, and a Geiger counter from them. The LCR tweezer is awesome, you can check the parameters of loose parts. If you have a random bag - you can quickly go through it and check the bits.

One word about scopes, especially Digital ones. The scope should have 5x The bandwidth of the signal that interests you. It's the little bits of glitch and fuzz on the signal that is useful to see. My guess is that this product will be great for Audio (or IQ signals from an SDR) but won't necessarily show you harmonics from a transmitter (for example). There was a QRZ article on scope specs awhile back. you may want to try and find that. Things like memory depth and sample rate matter. Don't go straight from a transmitter into the scope without an attenuator.

I was wondering if anyone had any experience with this company or its test equipment? I purchased a battery tester that measures internal battery resistance and it seems to work fairly well and has some nice features.

They have a relatively inexpensive oscilloscope that has decent features, if it performs as advertised.
