Yes the sampling rate is pretty low and I consider the useable bandwidth to be only around 1MHz.
The fact that it offers a DVM function and multiple measurements units and RMS is useful.
The key features for my needs is the Wi-Fi connectivity and it is self powered. Very useful when working on SMPSU's, but the inputs are not isolated from eachother.
I own a wireless DVM that was produced in the late 1990's. It has a transmitter head and receiver/display module. It cost a small fortune back then and was intended for remote system node state monitoring whilst a central control host was used to set different node states. It turned a two man job into a one man job
The little wireless DSO/DVM may be low bandwidth but when compared to the cheap low bandwidth Chinese USB DSO's it is very cheap at £20. The Velleman 200KHz educational series USB DSO still costs £30 !
If anyone deals with situations that require isolation of the DSO from everything around it (except the DUT of course), or remote monitoring of a node, this little unit looks a useful item to have in the toolbox.
SIGROK indicate that they hope to support the unit in the future. The fact that Velleman have made the protocol public will help developers support it.
More once I receive it.
