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.

Wash first
Color: 25 Pack (Value-Toys)
These are excellent and very well made for a 1 and 1/2 lb Chihuahua girl. I don't know how much they would hold up for a bigger dog but they're perfect for a little one. We always wash all of her toys first and I didn't notice that there were garbage bags in there. Which ended up being a good thing because they were scented. Washing help to get most of the scent off and it took the scent off of the toys. She hates the scent. Me too. It was nice to have the doggy bags though and we would prefer them not scented. We didn't dry the toys and we let them air dry which is a good thing cuz it might have ruin the bags. The bags are a little small and short compared to the normal bags that you buy but overall this is a really good value and she loves all of the teethers and ropes very much. Very well made. Nothing has fallen apart and she has chewed it a lot. I don't know how it would be for a bigger dog but for one and a half pound puppy Chihuahua it's perfect

My little Chiwoxy (Chihuahua & wire terrier) loves them all!
Color: 25 Pack (Value-Toys)
I was a little nervous to order this set of toys, I worried that they would be sort of junky or dollar store quality. They definitely are not! My little Mia Bella loves this toy set. Her favorite thing to do is for me to stuff them all in the box they came in, so she can rummage through and each of them out one by one to play with. Empty box, starts all over again. There is a nice variety of soft plush squeakers, soft crinkly toys, ropes with rubber shapes on the ends, ropes with knots, and different kind of balls (some rubber, some rope, some soft plastic spikes). My puppy is very small and I was worried they would be too big for her - they are the perfect size and she loves each and every one of them. Also included were some rolls of poo bags and a plastic holder to hook onto your leash to hold them - I was happy these were included, I hadn’t noticed them on the description, so they were a surprise. I feel like these toys are a great value and provide a small dog with a lot of fun things to play with. The variety is great so you’re not having to spend money on buying a whole bunch of different things. I am very happy with this purchase, and I highly recommend it to anyone else with a smaller sized dog. I think they might be too small for a very large dog but who knows, they are likely going to be fun for any dog to play with.

Great selection of dog toys at a good price!
Color: 25 Pack (Value-Toys)
Lots of great toys for your little little dog at a reasonable price. Even comes with doggie poop bags. At any of my local dog shops just one of the ropes would cost me the same as the whole box of toys.

Excellent Variety Pack - Dogs Love These Toys
Color: 25 Pack (Value-Toys)
This 25-pack is fantastic value with excellent variety—ropes, squeakers, and different textures keep dogs entertained. They're colorful, well-made, and my dogs love them. The main downside is the chew resistance on the rubber toys isn't the best; aggressive chewers can break through them fairly quickly. That said, for the price and the sheer number of toys you get, it's still a solid buy. Perfect for rotation and keeping dogs mentally stimulated. Just know that heavy chewers might go through the rubber ones faster than expected.
