- Blackbox MicroSD Card Slot:
- *Betaflight firmware requires the type of microSD card to be either Standard (SDSC) or High Capacity (SDHC) under 32GB, so extended capacity cards (SDXC) are not supported (Many high-speed U3 cards are SDXC). Also, the microSD card MUST be formatted with the FAT16 or FAT32 (recommended) format. So, you could use any SD card less than 32GB, but the Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose 'Overwrite format' then format your card.

Confortable
Size: Standard (Mid Loft), Number of Items: 1
Excellent support. Always fluffy. It does have a smell but as recommended I let it air out for a day. I also washed the cover and had no issue.

Perfect latex pillow
Size: Queen Size
I’ve been using the pillow for about a week, and I’m really happy with it so far. It’s soft and bouncy but still gives enough support for my neck, which is hard to find in a pillow.
When I first received it, there was a slight odor from the new materials, but it went away after about two days, so it wasn’t a big deal at all.
What I noticed right away is how it kind of molds to your head and neck without feeling too firm. It’s definitely more supportive than regular foam or down pillows, but it’s not stiff at all. I also like that it stays cool throughout the night—I never wake up feeling overheated.
Overall, it’s a solid choice if you’re looking for a pillow that’s soft but not too soft, with enough support to keep your neck comfortable. Definitely worth trying if you’re picky about pillows like I am.

Our favorite pillows & we're picky!
Size: Queen Size
My whole family love these pillows, & we are picky pillow people! They are comfortable through the whole night & I get the best nights sleep. We even put them in our AirBnB house & guests ask where they can buy one. I highly recommend. They are soft on your head but still supportive.

Excellent pillow
Size: Queen Size
I have now been using this pillow for 6 months and I’m very pleased with my purchase. It’s all one piece, not shredded material that shifts. Stays exactly the same shape. Bouncy & not too thick or thin. Stays cool. I don’t plan on ever using any other kind. I sleep so well and no neck pain.

The PERFECT Pillow!
Size: Queen Size
As I grow older, I was waking up with a sore neck. I tried a variety of pillows including feather, fiberfill and memory foam, but Latex was the best by far. Now to find the perfect Latex pillow... First I tried Dunlop Latex but found it too firm. Then I tried 2 different Tatalay Latex. One was soft until my head sunk down, then it became too firm. The second one, this one, was PERFECT. Soft but not too soft, and my head never bottoms out. Feels like my head is floating on air. And no rubber odor. There is a slight scent initially but it isn't unpleasant. I've been sleeping on this pillow for 10 days now and have never slept better. I don't find that it's any warmer than any other pillow. The pillow comes with a nice soft stretchy cotton cover.
(I purchased a spare pillow for the future).
