Customer Reviews
GOOD QC and it work well
Amazing
I love how small the item is and it has all of the features I was looking for. I especially like the fact that I can connect and control the device through apps on my phone.
Very good! I recommend it.
Works like expected but the silkscreen on the button side isn't as depicted in the listing. It just has the url for the chameleon ultra github printed on it
Thank you for your feedback, Michael. We’re glad to hear the Chameleon Ultra V2 works as expected, and we’re sorry the silkscreen design was different from the listing photos. Product markings can sometimes vary slightly between batches, but we understand that the images should match what customers receive. We’ll review and update the listing photos to make this clearer. We appreciate you letting us know.
