Customer Reviews
Brilliant little bit of kit for the price. I use it for repairing vintage synthesizers and the 10MHz bandwidth is more than enough for audio signal paths. Much easier than dragging my old analog scope out.
Fast delivery to Wales. The 'Auto' function works perfectly for finding signals quickly. It's become my go-to for automotive diagnostics when I don't want to set up the laptop.
I bought ten of these for our undergraduate lab. They are robust enough for student use and provide a much better hands-on experience than sharing one expensive benchtop unit.
Great value. The screen is surprisingly bright and clear even in a well-lit workshop. Only wish the probe cable was a bit longer, but it's a standard BNC so easy to swap.
Better than the cheap pocket oscilloscopes you see on eBay. This feels like a proper instrument. The UK warranty gives me much more peace of mind.
Solid performance for DIY electronics. It struggles a bit with very high-speed digital signals above its rating, but for general Arduino and PCB work, it is perfect.
Excellent customer service from the Probeo team. They answered my technical questions about sampling rates within an hour. Highly recommended UK seller.
