Hoping somebody might be able to give some experience / guidence around a couple of products we are looking at buying

Im very much from the spinal tap school of electrics and tend to turn it up to 11 and whilst we have some great options in estim 2b and an erostec 312 box myself and a particularly sadistic lady are looking at some other options which sacrifice some of the nicities and pleasurable elements of the named boxes for a little more of a brutalist approach.

For context we use shock collars and cattle prods a lot and have used stun battons / guns on numerous occasions so are not naive to the risks and responsibilities that come with such type of play and as such we have in mind two options we are looking at and Im hoping somebody here might have experience of them

The first is the X1 screamlabs box

https://www.screamlabs.co.uk/ModelX1.html

This has a signigigantly higher output (in max mode) to an erostec and im told delivers the power in a much less smooth way making it doubly hard to cope with. - That massivley appeals for us as doe the asthetics and the sound it makes when being used.

Somebody recently reccomended an alternative to me though which is the Dom Orgel (the dom organ)

Which essentially seems a slightly more BDSM friendly version of a tucker telephone and that also really appeals to me - something about that hand held go anywhere manually driven box of pain...

I again like the asthetics mirroring the old field telephones and the price is signifigantly lower than the screamlabs

does anybody have any experience or thoughts on either of these boxes - or indeed alternative suggestions (beyond the generally available estim boxes as we have experienced pretty much all these are and activley lookinf for something a little nastier)
