The Xiaomi Mi 4A Dual Band Wireless Router allows you to reach 300Mbps over the 2.4GHz band and 867Mbps over the crystal clear 5GHz band, the max wireless speed is up to 1167Mbps over both. The 2.4GHz band offers transmission over greater distances, with better coverage and better penetration through walls, while the 5GHz band adopts 802.11ac technology giving you less interference and higher speeds for a smoother experience watching HD videos and playing multiplayer online games.

The Mi Router 4A supports Smart Connect, offering 2.4GHz and 5GHz bands under one Wi-Fi name. This allows you to have no more confusion over which Wi-Fi network to connect to 2.4GHz and offers better performance through walls, while 5GHz provides higher speeds. The optimal frequency band is also automatically selected by a dual-band terminal.

The router comes with 4 external antennas so that the signal can travel through walls better. 4 external omnidirectional antennas, which are precision tested, and with a carefully designed internal structure and configuration greatly improves transmission performance, even in complex environments. It also features dual cooling fin heat sinks for better system stability and cooling. A specially treated metal substrate is combined with nanomaterials boasting exceptional thermal radiation features. It offers both excellent heat absorption and heat dissipation capabilities to effectively lower the chip temperature and provide improved system stability.

The perfect toy for dogs!
Style: The Duo
This is perfect when you have 2 dogs who love to play Fetch! They no longer have to chase after the same ball! The balls that come with it are very sturdy, and the launcher sends both balls far enough away so that both dogs get plenty of exercise. It’s definitely worth the price!

PERFECT RETRIEVING TOY
Style: EcoFetch
You can barely whip it and it sails far and fast. This is the perfect retrieving toy for my GSP. She's used to average and we now have a small yard, so the dog park is where she gets to run hard and fast. You can also throw tennis balls with it, which is a plus for when her sister steals her ball. 5 star fun!

Easy to use for this old folk!
Style: EcoFetch
If you have a hard time to bend down and throw, this is perfect! It allows you to pick up the ball with little bending over. It also gives much further distance to your throws. Great quality to both the ball and wand.
