We had a decent response to our HMD post, but $400 might be a little too steep a price to pay for the Zeiss Cinemiser glasses. Luckily, Zeiss is offering registered Gizmodo readers the chance to try them out free for two weeks. All you have to do is comment on the Gizmodo post announcing the offer with a registered Gizmodo account, then fill out some information on a form Ziess has set up for this offer. Of course, you have to provide them with credit card information (just in case you break the glasses) and a great deal of feedback from the experience, but it’s far more preferable than shelling out $400 to find out you don’t like the glasses.
