Pros: It works. The option for audio or just the blue light is good. Price is very good and simple to setup.

Cons: My first one, button was broken but, friend fix it. After six months the charge lasts less until recharged next sunny day. It now activates three times and dies. It is a bit sensitive per any branch motion.

Overall Review: I really wish there was a battery operated option for indoor. I bought another one hoping someone can help me rig it with a battery for indoor. I have it mounted on an eave facing the gate from the inside. Next to a voice alert sensor alarm and Smart-Guardian 120W SmartGuard Motion-Activated Light with Camera and Audio Warning. Oh, yes and an armed big canine.

Pros: It was a good price back on May 2009. Capacity was outstanding.

Cons: Before the year, my card started showing rare and random image corruption. Eventually, after many reformats with windows and my Nikon D300 reformat feature. I risked taking photos while I had an assistant back me up. Regrettably, the card came out with a blank folder and no images. I bought a data recovery software (MediaRecover) and rescued most images except the three most critical shots. What were the odds? I tried to get an RMA from Ridata and the form is not functional. I get the impression that it was designed purposely to discourage dealing with the problems. I sent an email to give them a chance. I will update if they bother to reply and make good on warranty.

Overall Review: I have bought three Transcend 8gb cards in the past with no problems. I own two Lexar Pro 8gb, three Transcend 8gb, SanDisk 4gb, TwinMos 2gb, just bought a Transcend 32gb to replace RiData 32, and countless cards since 2000. This has been the only one to fail. This is the first time since I 2003 that I have bother to write a negative review. I wish I did not have to.

Pros: Cheap

Cons: Exactly what I was looking for. Too bad it came dead on arrival. Took over two weeks to make way from China.

Overall Review: Downloaded software, prompt me to restart computer and was not recognize soon after. Use two other computers. Windows 7 and 8 and it would not appear. Took to long to get here from China. First bad experience from foreign country purchase. Then I realized that it was more than 30 day policy.
