Well, it is a DSO with basic functionality, and it even does display signals. The built-in AWG basically works too, within the limits of its design. Despite various deficiencies I can live with the device. I got what I paid for (~140€ about two years ago), so I must not complain. Of course you can always find better ones. Even if you already own a $10,000 model from a prominent brand, you still can find better (and more expensive) ones. You can only expect advise, if you can clearly specify your requirent. Nobody can know what you need and what you want to do with it. And your budget will certainly play a role too. Now that you have it anyway, why not just test it and judge yourself? Either it is OK for you, or it is not.
If you do know that 64k points sample memory won't suffice for your use case, you should not have ordered it in the first place (but if you don't know, then you probably don't need it - at least not yet). And if two occupied USB ports are not an option for you at all, you should not have ordered it either (in the handbook which is available for download this was well visible in advance).
