Wouldn't all software be better if free?
While it is debatable whether a lot of software packages are worth the price you pay, especially if you are a private person, I think USB Safely Remove is both very cheap and well worth the money spent.
There are many small utilities that easily cost more than USB Safely Remove and contains only a fraction of the functionality seen in this product.
I personally would not mind paying the small fee for USB Safely Remove to support further development of an already very good product
