Having not had any experience with the unit you mention, nor the software I cannot comment directly, but I know there have been threads over at
smartstim.com regarding the provence and safety on the unit. As it appears to offer 'more power than a ET312', I would be concerned that the unit does not have the same levels of safety in the design present on our
2B or, even the ET312, especially when reading some of their sales blurb.
There are a couple of interesting threads here discussing the unit
http://smartstim.com/forum/viewtopic.ph ... im#p235706 and
http://socialstim.org/content/bt-stim-box, but bear in mind that BigTip, the author of may of the BTstim treads on the socialstim site is heavily involved with the promotion and distribution of the unit. (As I am with the 2B, but then I do disclose that!!)
The socialStim thread makes heavy play of the fact that the BTstim box does not 'alter' the in coming waveform, and allows the range from 50-5000Hz to pass, where all the other units clip the output. Well firstly we (the 2B and to an extent the ET312) clip the higher frequencies for a very good reason, they cannot be felt but can still cause damage, and secondly all amplifiers will change or distort the driving waveform, so to state that a box doesn't is incorrect, and does no reflect well on the design of the rest of the unit.
Incedentally I wouldn't be paying $349 for a stereo stim unit that can be possibly made from designs on smartstim for less that $50.
$349 is a very high amount for a basic stereostim unit (adding lights in my opinion does not make it 'advanced'), especially when you can purchase a 2B for $399, a unit that is upgradeable, offers more modes, higher levels of safety, is well known and comes with a strong customer following, and a lifetime guarantee.
In the end there is a big difference between a commercially produced made for play unit like our the 2B, ET312 and what appears to be a more home made 'stereostim unit'. Stereostim does give a different feel to e-stim, but is much more dependent on the user/driver to get good results safely.
