Very well packed. Quick delivery. Product looks good. Tested up to 25MHz on sine wave. Other wave forms don't look too good at 25MHz (but that could be my oscilloscope). The controls are reasonably intuitive (I haven't looked at the manual but could access most of the standard functions). The case part for the mains socket could be a bit more rigid because it flexes under the stress of inserting/removing the plug. It seems to start with default amplitude of 10volts which is quite high (that may be a configuration setting which I have not found yet) Anyway, for the price, I am very pleased.
