I really LOVE this board! We use it in our EOC and it is a tremendous help for planning and meetings. Being able to draw on the big screen maps is invaluable. Zoom meetings are easy too and we can easily see the presenter and participate with the attendees.
My husband loves it
An absolutely amazing addition to our homeschool. My son absolutely loves it and it makes schooling so much easier . The split screen is my fave cause I can be showing him and breaking things down on the same screen . Thank youGreat value , extremely functional.
Bought this back in march. It’s been great but often freezes and needs me to reboot. The other main issue is lagging, specially on any video call, but also generally.Is this a one-off issue with my device?It’s not useable on any video calls because it lags so much.
This board is a game changer for my company and is integrated with all the most popular apps you need to run your business. I highly recommend this buy. Worth every penny.
