Some months ago, i bought a "Vice" from Lockedinlust, and could escape easily!
Years ago, i had a CB3000 with some Spikes. That was more secure and way cheaper!
Now i am using a metal cage from edd24 with some spikes, and this is the first one for me, that is really inescapeable!
First, there is no space to get your balls out, and second, you wont get your dick out, without the spikes cutting deep into it...
