Is there a better site for free download of patents in PDF format other than http://www.patentretriever.com ?
Patent Retriever http://www.patentretriever.com does not require user registration and is simple and fast to download patents in PDF format. Are there any other sites that can offer the same?

I've used quite a few sites for work in the past. However www.patentretriever.com is a lot easier to use without the annoying registrations. It does the job quickly and best of all it's free. Other sites just waste time or are too complex to use. That's probably why it is so popular for people who need to use it for work nowadays.
