I've had this 'scope for about 10 years. It generally works well but I've been using a Picoscope more recently.
It works well. There are a few minor issues with it.
The battery has degraded a lot so it will only run for 20 minutes or so on the battery. It's charged and run from a standard IEC lead so it's not a problem if plugged into the mains.
The vertical position encoders don't move the traces smoothly when moving a long way, but the're fine when moved slowly.
The fan is a bit noisy.
One of the leads hasn't got its original clip.
The USB connection can be a bit unreliable, but I managed to use it to get the screenshot. The 'scope needs a USB drive that is formatted FAT32
The plastic front is a bit discoloured with age.
£100 plus postage, or make me an offer. I'll put it on Ebay in a week or so if it's not sold.
