Be VERY careful with the credibility of this website. I caught the website creator - Justin Thomas - doing some very deceitful and underhanded things with older reviews. Simply put, he changes the title of the review to make them seem brand new. Case in point. I was looking for rechargeable batteries. I found his article "The Best Rechargeable Batteries and Chargers Of 2009" but it had a December 2006 authoring date. I contacted the owner and he then changed the authoring date to a December 2009 authoring date (more than likely to shut me up and hope that I go away). What striked me as odd is that he changed the date to reflect one day before I emailed him. Hmmmmm...very suspicious. So, I started to dig and check and compare. Lo and behold...there were comments from readers that PRE-DATED the date it was written. How is this possible?!? On top of that, the comments section had already been closed. Now, tell me, why would a comments section be closed on a supposedly very new review. I contacted the website owner again, regarding what I had found and got an email reply (which I have kept all) that basically said, "hey, if you don't like the reviews I put on my website, leave and go elsewhere." To top it all off, he was advocating the Rayovac I-C3. I called Rayovac, because I could not find that product anywhere on their website, and I was told that this battery was introduced back in 2003!!! And they have discontinued making it as it is now old battery technology. OMG!! I was so pissed, but that phone call to Rayovac pretty much confirmed that Justin Thomas was posting fraudulent reviews by claiming they were newer reviews than what they really were. Well, I was just at his website again and he has...YET AGAIN...changed the date from a December 2009 back to a November 2009. This guy is truly jerking people around. Stay away from anything reviewed by this guy or his website - Metaefficient.com. I recently came across an article that stated that he doesn't actually do any testing himself of these batteries. Again, don't trust this website for accurate or up-to-date reviews!!
