Smashing Commerce — ineffective pest repellent device

This product is too noisy & ineffective. I exchanged several emails for refund with these guys but they email me the standard copy/paste emails totally irrelevant to my complains. These guys are a bunch of con. Do not buy any product from smashing commerce. It’s a pure waste of our hard earned money, time & patience. These guys just don’t care after the receive the money from us. No one answers the calls, it’s very apparent that these guys are doing this business to con people.
