These echo chambers used to retail for £49 some years ago but a special purchase allows us to sell them for just £29!
Here's our Youtube Demonstration of the EC-990 Echo Chamber (applicable to all versions) For the first 5 minutes i talk about the different versions we sell - giving lots of info about them & which version you should choose, along with some useful general info about these Echo Chambers, so please watch from start to finish at least once, but after that if you want to go straight to the sound demo, go about 5 minutes in and you'll be there! ... enjoy!
I originally made this video for eBay where we also sell these (at a slightly higher price than on this site), so please excuse the "ask seller a question" references etc!
