The only problem I found with Ashampoo products was the incredible amount of "special offer" spam that filled my inbox after I registered the software.
It works well, and I really like the product, but I had to get really unpleasant with someone at Ashampoo to get them to stop sending up to 10 emails a day. Unsubscribing didn't work the 5 times I tried.
If I want more stuff, I'll buy it, y'know? But don't nag me.
