EZCast is a competing technology, in some cases it's packaging is just a clone

Dongle acts as ap/wireless router in order to use it.
Client app connects to EZCast wifi and EZCast dongle is connected to home/office wifi network.

EZCast dongle examples:
EZCast M2 III
Measy A2W
Tronsmart T1000
Vsmart v5II
and dozen of others, some even with external antennas.

These dongles are often advertised as Miracast dongles.

Chromecast vs EZCast(tronsmart t1000) review
http://liliputing.com/2013/12/tronsm...-giveaway.html

------------------------------------------------------------------------------
Security - In terms of security both products are flawed:

*Chromecast acts as open AP if is not connected to, in case of rooted it allows to steal your ESSID and PASSPHRASE
*EZCast(Measy A2W in my case but it's just EZCast standard)

EZCast is by default protected by WPA2 and 8 digit passphrase which is fair.

Dongle acts as ap/wireless router in order to use it. Client app connects to EZCast wifi and EZCast dongle is connected to main wifi network.

1. EZCast Dongle has for some unknown reason WPS enabled.
WPS is broken/hackable via WASH/REAVER since December 2011. Fixed in firmware 13886 (Aug 2015)
2. EZCast has always the same ESSID(should be an option to change it), also 32 characters limitation.(fixed in 2015)
3. It's not possible to hide ESSID broadcasting.
4. Passphrase to it's network is always limited to 8 ASCII characters, which is too short, should beup to 63ascii/64hex characters.
5. AP that EZCast can connect to has to be about ESSID 16 character long/16 characters long, should be ESSID 32 chanracter long and passphrase 63 ascii or if 64 hex character long.
6. After dongle factory reset initial WPA2 passphrase is always the same(returns to stock value), should be randomized.
7. I find it strange that iezvu .com collects unique ESSID, email, IP, while default WPA2 password is the same after each dongle reset.

Probably there is a correlation between ESSID, MAC and passphrase - guys from RouterKeygen are good at finding this....

------------------------------------------------------------------------------
For mirroring desktop/expanding desktop EZCast is superior to Chromecast Stream can be about 30 - 35Mbps.
You may stream up to 4 desktops at once to one screen1/ split 2/split 4, I have tried only 2 at time.

------------------------------------------------------------------------------
If it comes to playing movies (nearly all formats supported) with EZCast Windows it runs fluid in Video Mode, but without subtitles.
It's also possible to watch movie with subtitles with screen mirroring but it's not so enjoyable - slightly tearing.

You may also stream audio files.

It's supposed to be better from Android phone but i just have tried audio/video/camera live stream

------------------------------------------------------------------------------
Video cloud storage playback is available in android and it is fully enjoyable. YT, Vimeo, around 50 sites supported. It works in similar way as chromecast.
Even more sites supported for Chinese consumers.


For cloud video streaming for this moment Chromecast may be a winner, but EZCast is in active development - monthly cycle. Chromecast development is still slow.

------------------------------------------------------------------------------
Price of EZCast dongle is about $30-$35 so it's very similar to Chromecast price.

measy a2w + mtk6577
I have the measy a2w. miracast works well with android 4.2.

But for my 3 phones/phablets with mtk6577 chip and running android 4.1. It was difficult. The EZcast app wouldn't install. I figured out how finally. I had to add the .apk app file to /data/app manually and set permission to rw-r--r--, then reboot.

The manual is a joke, as always. It doesn't even talk about miracast.
settings > display > wireless display > search device > connect
That's all it takes for android 4.2.

Ok this kinda suck then if subs dont work the way it has to.
I'm half deaf and I need subs to understand what they are saying.
If they can't fix this, then it's not worth to buy it.

I've seen the video on Youtube and it's just a tutorial how to get it work and that's it.
Some functions are not explained well...or if it exist.
It's more like 'look we got a chromecast copy and this are the functions and some will not work''.
If they want to sell a product, then they have to take the time to show it so people can say WOW...worth the money.
But no you get questions after questions.

Anyway...lets hope most video player apps will add chromecast support asap since Google released the developers kit.

In full screen mirroring its possible to watch with subs, its just not too enjoyable while dynamical motion, its much better than chromecast full screen or tab mirroring.

AH I forgot about the mirroring!
But the quality won't be that good if you have to mirror it instead of streaming the video.
The other thing with EZcast is that it doesn't take over all the work like Chromecast does.
So your phone is still consuming power to run the media? Correct me if I'm wrong.

You are probably right(i have not tested it with android.) You may ask on their (iezvu) forum. I bought Measy A2W (EZCast dongle) because of decent screen mirroring and flawless movie playback with any format(on PC i did not succeeded to use subs) , things that Chromecast is totally missing.

I have the Ezcast M2 and it works flawless if I'm near my wifi router, but if I'm downstair, there are massive lags when viewing in 720p and higher. It kept buffering. I believe Miracast acts more like bluetooth which is based on distance I wish there's a way to improve this. If anyone have any idea how to fix this lag, please chime in.

Be sure it's updated to 11391, place it not too close to the wall/floor, you may use hdmi extender for tests.
Generally this device should be placed in line of sight not another floor.
It depends on how good is wifi adapter is used. If its not in 802.11n(150Mbps+) or newer such as 802.11ac card there is high chance for lags.
Cast movies via Video mode not mirror screen mode.

I have my ezcast plugged into my Yamaha receiver to have surround sound, and the router I have is a linksys e2500 dual band. I have most stuff connected through the 5ghz channel, leaving the 2ghz dedicated to guest and ezcast or any other devices. Both bands are on wireless N only, and it's not pointed toward the wall or on the floor, it's sitting on top of my tv stand. My router is fine I have no issues with the roku 2 xs, just the ezcast is always buffering on 720p when streaming from youtube, and 1080p as well. I have the latest firmware and the app update as well. Any more suggestion?

Not much(I doubt it will help):
Update routers firmware.
Experiment with router position - should not be too close to wall/floor or other high density objects.

Be sure you use 40MHz channel width and experiment with different wireless channels.

cheap signal booster example, it'll be hard to direct it between floors

Alternatively just forget about it.
