Not Quite Pro...
The scope works well, albiet slowly. In XP the display is hard to drive, and it requires system push to make work well. I would not buy this if you aren't patient and don't have time to work a sticky program. The displays-second layer menus, and controls don't display without opening and closing the tasker. It might take a few seconds for each screen to reload in refresh, but all the controls, displays readouts are clean clear crisp and function properly, even the math. It was hard to figure out how to get it out of Chinese and into English. It does not have a calibration probe, and I found the unit to require 36 ohms of attenuation adjustment, at the probe, to calibrate it properly. Overall, I find this unit satisfactory for my needs and wants in a scope, but there is a small question that I still haven't answered yet...
What is the banana plug on the back of the scope for?(The picture of the one I bought didn't have a banana plug on the back, the one I received does have.)

wrong filter output
I have a large penn plax undergravel filter, that uses ammonia filters, but I can't find any the right size. These did not fit the output that my filter uses, I altered my old used filter so I can refill it with bulk ammonia after I got these, and they didn't fit. These look like good ammonia filters, and if they fit your filter output, they are great. They don't fit my filter. My filter uses larger cartridges.
