Looks good for what it is (you have to understand what it is and what it is not.)
The specs on the scope or pretty low end compared to even an entry level "real" scope. This device only as 100M samples per sec and 30 MHz bandwidth where as a $300 DSO from Rigol has 100MHz bandwidth and 1G samples per sec. The Sample/sec spec really DOES matter especially off you are using multiple channels as that sampling rate is the TOTAL rate not the per channel rate. Even 1G/sec is low for a 16 channel scope This device would be very useful if you do mostly audio work or need to decode a serial I2C or SPI bus or if you are looking at PWM and machine control signals that never really go above 1MHz But notice there is no way to hook up a real scope probe. You are NOT going to get clear signal into the box unless you can connect a 10X probe. Mini grabber hookups are not scope probes. They are OK for logic signals but not analog. So notice how short they are, there is a reason for that. Also notice there is no vertical amplifier/attenuator on the box like you'd find on "real" scope. So you might not have good sensitivity for millivolt level signal and can't connect high volt signals (like the ones going into motors) The input range is small. BUT you can build something to condition the signals even as simple as a voltage divider and denier diode clamp. to allow a 100 volt range. That said, looks to be worth it IF you like the software and it looks like you can download and try out the software BEFORE you buy the hardware. There are competing products but this look like one of the best in its class, Saleae has an 8 input unit for a little less, and 16 inputs with 500M sample/sec for more $ and ee101.com has something too that looked good. Depends on what you want to do mostly There are LOTS of these out there. Tis unit is not bad for low speed logical level stuff, debugging firmware and such. I ended up with a Rigol D1000z scope, has four analog channels and 1G/sec samples and can move sample data to PC over Ethernet if needed and with my 100x scope probe I can directly and safely connect to the insides of one of my vacuum tube amplifies with 600 volts inside. Oh and I bought a a Saleae clone on eBay for $12 that works well for low speed logic level signals.
