Caputron is excellent....

ActivaDose II Review

Their customer service is excellent, the shipping was quick and accurate in relation to their estimated arrival date, and the product has been reasonably-easy to figure out. Given that it is of a medical grade, I feel secure in learning about how the device works!

Works well

The device works well.

Works as expected

I ordered my ActivaDose starter kit just over two weeks ago. In the two weeks that I've been using it I've had no issues with it. It works as expected.

I see and feel results

The device and the caputron accessories work well together. The booklet in the kit is not very applicable or useful. I needed to educate myself through Google and you tube searches. Despite that, I am happy with the results so far. Actually, amazed that it works at all and pleased with results. I would suggest keeping current down to one milliamp and time down to 20 mins until you get used to it. Current is affected by saltiness of the water, so you may want to buy saline, so you have a standard. I'd like to hear from others your experiences. Thanks
