good for learning or playing, but I can not recommend for real work

I bought a DDS140+function generator 2 month ago. First I have a problem installing, because it wont work in any usb 2.0 port, in my case on my lenovo laptop it works only 1 usb out of four. The support did not answer at all, so consider, there is no suppurt! The hardware anyway could be good, but the software is an awful one. It freezes a lot, I always have to **** then restart, and measurement in screen is useless. I got the newest software on the CD, version 1.4, but in the web the newest version is only 1.2 I measure 50Hz from the wall outlet with a 1:100 probe, and in measurement window it dislplays it is 50Hz, in the screen measuring between the two point it measures 22ms, which is definitly not 50Hz. It is not a hardware problem, it is just the software, but the point is bying a digital storage oscilloscope is, exact measuring. This is the weakest point. Software is bad, no support, no updates. :( I wont buy it again this product.
