Interesting. I like the idea as a generic tools that can be used with different devices (laptops, cellphones, etc).

$99 extension for jamming $50 Echo Dot is a bit too much.

Counter Attack: Since Alexagate doesn’t interfere with the Echo's speakers, Alexa can play a music that has clapping in it :P

Yea, $100 is kind of a lot, which is why we priced our smart speaker blocker at $40. It's called BuzzOff and is available at buzzoff.info.

Cool, I just noticed that Buzzoff is as bulky as Alexagate. Is there a reason for this?

With my naive understanding, I was expecting a more generic device that can be placed close to any microphone (laptop, phone, smart speaker, etc) something like this IKEA usb lamps : https://www.ebay.com/c/1278841657

How do you mean bulky? BuzzOff is 14mm thick, sits under your Echo and doesn't require a separate power plug. Rather than blasting ultrasonic noise, BuzzOff shares power with, and controls the power flow to, your Echo.

We could make BuzzOff quite a bit thinner, but the Echo power plugs are the limiting factor, they are almost 10mm diameter.
