I have the multi-piece cheap kit with the angular dongle - also a cheap Chinese commodity and probably precisely what Wow is selling, but at several dollars less after shipping and with better Amazon return policies - coming in a few days and will report then.
One addendum; the EEEKit unit (and presumably the Wow clone) uses the charger to power the dongle, but doesn't seem to use it to power the tablet. The one-piece red unit (Skiva et al) does power the tablet via the cable... which would be more useful if it also worked for it's intended purpose.
Has anyone confirmed successful use of a One Piece Micro USB MHL to HDMI converter/cable other than the $40 Samsung OEM one? I have a Samsung Galaxy Tab 10.1 Pro and want to push video and audio to HDMI without carrying around three items (as is the case with this solution that seems to work per other posts: http://www.wowparts.com/mhl-to-hdmi-...-pro-8-4-10-1/).
