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.

Dermatologist-Recommended, Gentle Coverage with Added Sun Protection
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
This Eucerin Tinted Moisturizer was recommended to me by my dermatologist after having MOHS surgery performed on my face twice. At that point, sun protection became non-negotiable. He felt that the moisturizer with SPF 30 that was already part of my skincare routine was not sufficient on its own and suggested adding this product for better daily protection. I’m so glad I followed his advice. This tinted moisturizer provides lightweight, natural-looking coverage that evens out my skin tone without feeling heavy or settling into fine lines. It blends easily and leaves my skin looking healthy and polished, not made-up. What I appreciate most is how hydrating and gentle it is. My skin can be sensitive, especially after procedures, and this has caused no irritation or breakouts. It wears comfortably all day and layers well with other skincare products when needed. The coverage is sheer, so it won’t replace foundation if you want full coverage, but it’s perfect for everyday wear and gives me the confidence to step out with minimal makeup while knowing my skin is protected. I would highly recommend this to anyone who has sensitive skin, a history of skin cancer or procedures, or who simply wants reliable sun protection with a natural finish.

The Lazy Makeup Day MVP
Size: 1.7 Fl Oz (Pack of 1)
This has become my easy low-maintenance face day product. It gives just enough tint to even things out while still giving solid SPF coverage, so I can skip foundation without feeling totally bare-faced. The finish feels lightweight, my skin stays comfortable all day, and the color blended into my skin way better than I expected from a “universal” tint.

Overall good aesthetic result for mineral sunscreen, but some downsides
Size: 1.7 Fl Oz (Pack of 1)
It is quite good overall, it blends in perfectly to my medium-light warm tone skin. There is no white tint. It seems effective in terms of SFP and doesn't leave a greasy or heavy feel, ends up looking lightly glowy but reasonably dry to the touch. I'm not sure you'd want to apply it thick enough to substitute for foundation. What I don't like - Like makeup the color can rub off on clothes etc. - Doesn't seem to reapply very well, leads to pilling, and also rubbing my face at all leads to pilling. It's very "don't touch it again after you applied once" - Quite hard to remove with normal cleanser, I think I might need to remove it with oil or something?

Way too heavy & greasy for combination skin
Size: 1.7 Fl Oz (Pack of 1)
Ugh this tinted sunscreen is such a let-down. I was excited to find an option that's a mineral sunscreen, with tinting that's supposed to work for all skin tones, is made with non-comedogenic ingredients, and is a more reasonable price than what my old tinted sunscreen now costs. I saw mixed reviews on the greasiness / heaviness of this sunscreen, but decided to give it a try, especially because I have combo skin that gets pretty dry in the winter... but wish I had listened to the people who said this is overwhelmingly thick. Pros: the tint works fairly well for my light-to-medium warm-toned skin (although you can see in my video it doesn't blend at all well with my hand's skin tone... so can't imagine this will be universal), it doesn't irritate my combination skin that can be very sensitive, and hasn't blocked my pores. Cons: This feels like I'm smearing peanut butter on my face - it is such a thick and oily consistency. I have combination skin, with some areas that are especially dry right now in a northern winter climate... but this is not what I would call "moisturizing" - it's greasiness that is impossible to rub in, doesn’t dry down, and instead just sits on the skin (and I'm not even using close to the amount of sunscreen you're supposed to in order to get the true SPF coverage). I use tinted sunscreen to replace the need for a BB cream or foundation, and this unfortunately would never be appropriate for everyday wear.
