Hi,
I've owned a 2b for a couple of years now (2 or 3, I can't remember). Up until the last month or so I couldn't take more than 40-50 on my cock and about 70 in my ass without screaming blue murder. Now I can take everything set at max, even on my cock. Any mode, any feel setting. I've even setup with a loop and a pad on my shaft right near the head and a small pad directly on the head as the common in a triphase setup, max power isn't an issue even then at any feel setting. The only changes that I think could possibly affecting this are that I've started taking cialis once or twice a week, I've lost weight, and I've started taking ADHD meds. I'm sure I'd started the ADHD meds before it started feeling less powerful though, and it still doesn't feel as powerful without an erection so i'm doubtful it's the cialis. I regularly go 2 or 3 days without using the 2b. i'm also using the official psu. I'm just wondering if it's normal to build up a tolerance like this or if my 2b or psu could be on the blink?
thanks
dls
is it me or the 2b? (have i built up a tolerance?)

I've had my 2B for 3 years and enjoy stimming for a few hours almost every day. I have not noticed any change in the way it feels.
Check with E-Stim as it might be a technical issue.

Hello to another UK member, welcome
My 2-B is about 4 years old & is mainly used on mains power. Are you using on the High Power setting? Have you tried a new set of cables & fresh electrodes? If you have a fresh sticky pad, suggest you stick one on inside of left & right thigh, use something like Throb & wind up the juice. See how that feels. For me that would make my leg jump! as suggested a line to Admin to sort. As to meds I also take Tadalafil (generic Cialis) as necessary & that seems to work with my 2-B. Keep us posted with the result.

Re: is it me or the 2b? (have i built up a tolerance?)
There are several factors:
I do not know how medication affects sensitivity, but in general I would say yes, maybe.
Regarding electrodes: Yes, especially conductive rubber loses conductivity, mainly by mechanical stress, especially at the cable contacts, so it is a good advisory to replace them.
However, you should also expect to build up a tolerance for multiple reasons:
Like any other sense, it may get insensitive to a frequent and intense stimulation. Pausing estim restores previous state over time.
Also you should avoid skin damage ba lack of moisture causing burns.
And last the mental aspect, stimulation is felt more intense if new and unexpected.
If not operated by external power supply, exhausted batteries are an obvious cause.
Although I do not remember such reports, device defects might be a less probable, but not impossible cause.
For a forum user it is difficult to decide what happens in your case, but with the hints, you might find out.

For me I find my tolerance varies. Sometimes I cum at 20% and other times I have to ramp it up to max. I’ve had my 2b a couple of years and I’ve not noticed any changes to sensitivity over time.
I did once overdo it and shock my cock way too hard for way too long, that left it numb for two days which was quite scary…although also weirdly cool!
I do find a tiny change in electrode position makes a massive difference.
Program obviously matters two. I can easily do high power pulse on 50% but try that on throb and you can hear the screams from outer space,

I've been stimming for a couple of years now and the only difference I've noticed is that I need to go up 2 or 3 percent to get off, i.e. I used to get off at 32% and now I have to go all the way to 35%.
