**** DO NOT BUY AN BUY AN ANYTHING FROM THIS GUY**** I'm sure he will delete this so nobody will ever be warned.... This is a f*cking SCAM!!!! This guy has sold this SAME UNIT to multiple unsuspecting customers who expect to get a functional product that will rock a hammock. Instead it's a TINY solenoid that wouldn't even rock a freakin infant swing. When the customer is unhappy with this P.o.S., they return it - IN THE EXACT SAME PACKAGING in which it was sent - and expect a full refund. Then he charges a $30 restocking fee because you didn't send it back "as shown in the video". Soooo, he says it has to be refurbished!!!! THIS guy is making $30 SELLING THE SAME UNIT which gets returned, cleaned up, and resold!!! Meanwhile, his customers are getting screwed out of $30 PLUS another $30+ for return shipping because the damn thing is heavy - but NOT heavy ENOUGH to stay on the ground and rock a hammock!!!!! So his customers are paying $60+ for NOTHING!!!!! The product is a complete joke! Great scam buddy!
