Thank you for the interest in OPO! We are glad that you are here.
We are currently retooling a few aspects of the OPO product line that we know will make for a better user experience. We are committed to providing our customers with the best product possible. As such, we have removed this pre-order option until the launch of our new website in a few weeks. Thank you for your patients and continued support. Be sure to check back soon and see what exciting updates we have in store.
