I've compared every comparable product out there and this is by far the best value. It has features that I would consider basic, yet many lacked. Things such as manual editing of time information and different tasks under the same client.

The interface is very clean and doesn't get in the way. I haven't tried the invoicing feature, but it appears to be adequate, especially with a customizable template.

The price is more than fair especially when considering that an accurate count of hours would have saved me more than $30 in the past.
