Rikomagic RKM MK802 IV Android 4.2 Jelly Bean Quad Core Mini TV Dongle, RK3188 Cortex A9 CPU, 2GB RAM 8GB ROM, bluetooth

I hooked up a USB to ethernet adapter and got speeds 1/2 of what I was getting over wifi. Netflix, Hulu+, YouTube, foreign TV news apps all launch, but it's an absolute toss up whether the video will even load. Insufficiently reliable as a media player to keep it, going back to Amazon. Has a ping time between 300-500ms: abysmal!Edit 01MAR14: Couple of other things I noticed before I sent it back: It does recognize my HP webcam as both a video camera and USB microphone, BUT any app that can use video (camera, Skype, Yahoo Chat, etc) gives a "camera in use by other application" error - even right after a fresh boot. While the mic works to record voice, the latest update to Chrome Beta doesn't recognize it for the purpose of using Google Now ("OK Google") They've also tinkered with the OS to the degree that a lot of useful things are missing from submenus: Display: Daydream, SleepAlso, it is hardcoded to only use 3 specific screen resolutions: 1920x1080 1280x720 and 720x480 - I tried it on a few 4x3 monitors, it wouldn't sync at all with one of them, and showed a really squished/distorted display on another, so it must be hooked up to a 16x9 display. It does work with an HDMI to DVi adapter, but then there's no audio without a USB workaround or an HDMI cable that breaks out audio to a discrete connection.RikoMagic hasn't updated the software in about 4 months, and there's no word on a KitKat upgrade (don't hold your breath) and the upgrade process is heinous! Unix distros for it can't use accelerated video, so that's problematic (and probably void the warranty)It can't upgrade the OS off the SD slot or internal storage like an Android phone or tablet, the device needs to be mounted to a PC (Not a Mac in emulation, I tried) in developer mode and completely reflashed, then all your apps need to redownload from GooglePlay.The couple of times I was actually able to get it to play NetFlix it was stuttery, dropped frames, and locked up a few times where it would play the audio but the entire OS froze on a movie frame and I couldn't do anything other than pull the power to force it to reboot.Oh and even though it is listed as being 1.8GHZ - CPU-Z clocked it at 1.42GHZ so that's kinda sleazy and dishonest, no?

I just bought one in April 2014 and the serial number prefix was 201307, so it contained a real RK3188, not the RK3188T. As with a lot of these devices if you are an average user you may be disappointed or discouraged. The first thing you have to do is flash a decent ROM like NEOTV or at least update to the latest factory ROM. As far as the wifi signal strength there are fixes for the older models that require you to move the antenna inside the case. This was typically required with the first models (201305 serial number prefix), but you probably will not be able to buy these any more (the 201307 model has the antenna in the right spot). I found the best way to get a good signal is to start a large file transfer from your PC and orient the MK802IV in different positions and watch the transfer rate. You can get and app like Wifi Analyzer from Google Play Store to find the best channel for your router as well. It also helps to place you router as high as possible (6 FT or higher). There's definitely a range limitation of about 20 ft. if you don't do any type of antenna mod. Just moving the antenna outside the case gives you about 5x the bandwidth. I'd give it a higher rating if I didn't have to modify the antenna! A lot of the newer mini PCs have external antennas now.As far as heat, I found you need to keep the CPU at 1.0 GHz to 1.2 GHz or it will over heat. If you go higher than that then you will need a mini USB fan or heat sync mod.There a a several Linux kernels if you want to use this as a cheap Linux server or desktop as well...

So, I bought this item about 3 weeks ago and was very excited about getting it. I had been reading about this pc's on a stick for a good while, and the concept was awesome in my opinion. I hadn't purchased one before this point because even though I thought it was cool, I couldn't justify spending the money without having a real use for it. I am a Netflix subscriber, and use my Playstation 3 to watch that, along with Amazon Prime Instant Video, which is at least handy when Netflix goes out from time to time. I recently became interested in using HBO's instant streaming service, HBO Go, but Playstation didn't have an app for the PS3 to view HBO Go...guess what did? Android. Thus I finally had a reason to buy the pc on a stick.I went with this unit because it seemed to be the most advanced, being quad-core, 2 gigs of ram, etc. I was a little leery buying it so soon after it came out (sometime in late May), but I was so excited about it and eager to get HBO Go up and running on my tv, so I gave it a chance. I SHOULD HAVE WAITED...As for the problems...1. Like some of the other reviews have said, the WiFi signal is pretty horrendous. The theories have been either poor design causing interference, bad firmware, or both. After the latest firmware release on 6/20 it has improved, which leads me to believe it is more of a firmware issue, but the problems still prevent apps such as Netflix and HBO Go to operate properly. I also am upgrading my router to a good Dual-Band N router, so this may help the problem, but the netbook I'm currently using, my phone, and my PS3 are all on my current wireless G router without issues...I will reserve ultimate judgement on the WiFi til after I've hooked up the new router.2. Installing new firmware is very much a pain. Once you get the hang of doing it, it isn't so difficult, but the process is way too cumbersome to be a device in 2013. Doing this kind of stuff to update firmware on a device in say...2000 might be acceptable, but these days this process is near unacceptable.3. Support for the device is awful. The websites have some pretty severe Engrish. Some of the links link to sites that are in Chinese. The best form of support comes from the forums on the UK version of their website.What this really boils down to is it is a product that was released before it was ready, which seems to be a common business practice these days, even among large companies. Companies will constantly release software and hardware that doesn't operate as it should, thinking they can just do patches and fix problems. Patches should be to fix unforeseen bugs and such, not to fix complete hardware malfunction. If your product isn't ready for market, DON'T RELEASE IT YET. Being first to market means nothing when you get a product out the door that is completely useless without firmware upgrades. And trying 3 different firmware upgrades and still having a useless device is ridiculous. I've read reviews that the first version of the hardware that had Android 4.1 on it actually ran pretty smooth, but the one I got already had 4.2 installed on it, and it was terrible. Two firmware updates later and I'm still sitting with a product I've owned for 3 weeks and does not work properly. Even if they release a new firmware every week, doing the firmware upgrade is a pain in the neck. If they planned on releasing shoddy firmware and doing constant updates to it, they should have made the firmware upgrade process easier.My advice to anyone right now is to wait another month or so on this product. Let them get the kinks ironed out of the firmware and get some that actually runs the device as it's meant to be. It sounds awesome, I know, but I took a leap of faith and was sorely disappointed. At best this device is, in its current state, a toy for someone to tinker with, not a practical device for real-world use.
