I’ve been wanting this piece for a long time. At one point I used a makeshift piece like this for several months, and was super pleased with the functionality and economy of the design. The gravitron is a gorgeous design, much more elegant than its homemade counterparts. Functionally though it lacks the same efficacy, and comes in at a much higher cost than building your own. Glad to have a conversation piece, but I wish it were more functional than I’ve found it to be.
