I have been using IDM from from last 6-7 months.
Earlier that I was using some freeware download manager to download stuffs on Internet. Before purchasing IDM I used its trial version and I fell in love with IDM.
So I tried to buy it from their website but my card was not acceptable by their payment methods. So I bought it from snapdeal where I got it much cheaper with lifetime license. I can even update it to the newer versions. IDM helps me to boost my downloads to maximum speed. It does support all the popular browsers. I can even download youtube videos from IDM. I can able to download any type of file through the IDM. Following are the pros and cons which I have noticed while using IDM-
Pros:
1. Easy to use and simple user interface.
2. Can download any types of file and supports resumable downloads.
3. Built in Youtube video downloader.
4. Full download speed.
5. Supports proxies.
Cons:
1. No torrent support.
2. Little bit costly on their website. Get it from online shopping site.
