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.

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!
