I purchased IDM in Feb.07 and I've really enjoyed it till Feb. this year when it frequently crashed when I got Neotel. I then used FDM for a few months until the beginning of October when IDM started working 100's again.
All I can say is get it, it's worth the price. Free updates for life, updates every month. No need to purchase a new version every year. It makes the best of your line and reliable....well so far this month.
