RE: Site Speed - I purchased a 1mo subs. about 5mo's ago when we were getting ready to move into our new home. I needed to do some reading up on Washer/Dryer combo's and figured I'd spend the ~$4 for a 1mo. membership. Even with the membership, The site speed on some days was very slow and at times I couldn't even login (and I was on a broadband connection so it wasn't me). When I was able to get to the reviews they left me with more questions than answers. Many models were NOT listed or tested. I ended up having to do a lot of searching on groups.google.com and elsewhere for opinions. I guess they are having serious trouble in funding their tests.
FWIW, I also was looking for information on Baby Products (not just buying guidelines). It turned out that they hardly had any product information that I was looking for there either. Amazon Reviews and Epinions were very helpful in that category--Consumer Reports was a waste.
Also, if you ever do decide to subscribe you HAVE to cancel manually on the day you want it to end--not in advance. If you wait to long, they auto-renew and bill your CC. For a business setup to help consumers, I'm surprised they are setup this way. They should give the option to auto-cancel at the end of the month! I don't feel gipped, the one month fee was about the price of a magazine in the store, so, It's cheap enough. There just wasn't enough content for me to want a yearly subscription.
