- 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.

Inexpensive walls.
Color: Grey, Size: 34" - 3 Panel, Color: Grey, Size: 34" - 3 Panel
We had a hot request for a workstation in the warehouse with some privacy.
These have worked great. Easy to assemble. They are lightweight and stable.
This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.

Great value for price. Cute, lightweight. Could be used anywhere.
Size: 3 Panel, Color: White
Nice, lightweight. Good value for price. It's exactly what I needed for my hallway to keep my cats separate from each other. I used two zip ties to eyescrews in door trim and it opens up perfect to wall. Warm air gets thru and cats can see out/in. But can't get under or over. It's perfect for my use!!!!

Great seller and really nice items!
Size: 6 Panel, Color: White
These room dividers are really lovely. They are great quality and just perfect for providing privacy in a sunroom while still allowing light in to keep the room sunny. I highly recommend.

Nice divider!
Size: 4 Panel, Color: White
I use this as a "barrier" to keep my cat out of the guest room. I don't have to close the door anymore because the divider allows light and air through. Adds a nice touch to the decor, as well. Very lightweight and serves its purpose.
