I'll be honest i've been out of the loop with what's going on with the Swivi LCD, but it did get a fairly decent review from EOSHD.com. It basically adds a large 5.6" LCD to cameras that lack a Vari-Angle LCD, and provides Focus Peaking, and HDMI pass through. Below is the demo video about the Swivi product features.
Just got news that the Swivi 5.6" HDMI LCD is having a 24 hour sale (also includes LP-E6 type battery and charger). Most retailers are offering product from $370-470 dollars, but for the next 24 hour sale it's been listed at $275 via Amazon (Click Here).
Just posted a few days ago, YouTube member djteebz appears to be the first with his review on the little 5.6" external LCD. The video below is an unboxing, run through of the feature menu, along with some pros and cons with the Canon 5D Mark II.
Where's my Swivi Review? Well the Swivi has a built in miniHDMI male ended cable. This connects directly to any camera with a miniHDMI port, but because of this you can't use it remotely with a long HDMI cable. So before I posted my own review I ordered a small miniHDMI female to female coupler. (click image for product)
This little coupler (ideally) would allow me to use the Swivi as a remote monitor if I wanted to use it on a Jib / Crane. Well unfortunately shipping from overseas takes several weeks, and i'm still waiting. Swivi units are available on eBay (click here)
A video I shot several weeks ago, but decided not to post (the product wasn't announced yet). Now that it's been shown at PDN New York, here's a look at this unit with a Canon 5D Mark II + Battery Grip + Rode VideoMic Pro (showing access to audio ports). Keep in mind that this was possibly the very very first prototype released from the factory.
Shown in this video is a very very early mockup, and not completely relevant to the product being sold today. Software and build quality have been changed since. I still have not seen the final version, but supposedly it had great response at the PDN Show this past week. I hope to see a final version of the product once it's available online at https://www.SwiviUSA.com, which is said to be in two weeks.
