For US buyers, I suggest purchasing this from a reseller within the country. Mine has spent a month in customs.

Huh -- looks like someone's cloning the DSO nano. They appear to have three different configurations. It's anyone's guess as to what's really inside though...

1) The user manual is useless. You have to figure out how to operate the DSO NANO yourself. It took me two hours of trying but I am still trying to figure out how to use it. The manufacturer should spend at least two hours to write more instructions: this will save users’ time.
2) There should be a sentence to tell the users if the battery is charged or not, how to charge the battery and how long it will take to charge the battery. I plug it to a USB cable to link it to my notebook computer and it showed “Initialize, please wait…” After more than one hour waiting, there was still the same message. I unplugged the USB (with a fear of losing the firmware) and it was charged!
3) The on/off button is very hard to push. You have to use your figure nail instead of figure to push. Very hard.
4) I guess there is no earphone and microphone in the DSO NANO, but there are two signs there.
5) The probes are very fragile and very hard to use. They should be shielded since if you increase the gain you will pick up noises.
6) The bandwidth is only 1 MHz. For a microcontroller project, this is not enough.
7) It is cute and cheap.
Please do not post my comments since they are mostly negative. Please do not use my real name if you have to post them. If you have to use a name, just use “Xia”. Thank you very much.

1) The user manual is useless. You have to figure out everything yourself. It took me 2 hours to learn, try by error, but I'm still learning. The manufacturer should spend more time to write a detailed manual as it will save users' time. When I first got this unit, I did not even know if the battery is charged or not, so I put it in a USB linked to a computer. The sign is "system initialize, please wait ...". I waited and waited for more then one hour, still the same sign. With a fear of losing the firmware, I took it from the USB. It turned out battery is fully charged. There should be at least a note of how and how long to charge the battery.
2) The on/off button is too small, you have to use your finger nail instead of a finger to slide. It is pretty hard to turn it on and off.
3) There is no microphone and earphone in the unit, but signs are there. Why don't get rid of them so there will be no confusion?
4) The probes are too cheap, there is no shields. They will pick up noise from the air.
5) 1 MHz bandwidth is too small. It might not do the minimum measurement in microcontroller work.
6) It is small, very cute.
7) It is worth of the money.

I love my Nano!
If you have Nano or get one try out the "Paul" firmware it is quite nice once you learn how navigate it.
works well for most simple scope applications and great for hobbyist's!
And check out the forum for the Nano there is alot of info there if your curious.
GREAT WORK SEEED!

Ótimo produto! Deixa todo mundo impressionado! Pena que a alfândega barra e torna o produto bem mais caro.
