The SlimeVR Butterfly Trackers Campaign Is Now Live!

by Eiren

SlimeVR Butterfly Trackers crowdfunding campaign is live!

Based on the success and experience of SlimeVR Full-Body Trackers, SlimeVR Butterfly Trackers push the limits of comfort and ease of use for body trackers in virtual reality, motion capture, streaming, and more.

At only ten grams and less than seven millimeters thin, they are exceptionally comfortable, offer over 50 hours of battery life, can’t be occluded, and are affordably priced.

Reviews

During the month of January, we have shipped sets of Butterfly Trackers to five different independent reviewers and VR content creators. Sadly, January was a busy month and all of them for various reasons didn’t have time to make a review yet.

In addition to the five sets already sent, we’re sending one more this week, and up to ten more next week. We expect that independent reviews will be coming by the end of February, and we completely understand if you intend to wait for them before making your purchase decision!
