I found the following quote in a review on 405 vapors' website. I was wondering if you have, or are planning to, make any changes to the Hippo's design to make it more user friendly?
This is not a criticism of your product, and I'm sure I can get mine working fine when it comes, I was just curious.Posted by Jonathan Carcopo on 17th Jan 2013
It works, & makes anything you put on the provari look great, but it is a bit fiddly. You will need to take it apart. Secure the piece to the Provari tightly (pliers may be necessary to tighten it down enough to make proper contact with the 510 connector)
You may need to adjust the + pin on your device if it doesnt make contact properly. This will not be an issues with a genesis atty with an adjustable + pin (AC9) or a spring loaded one like a ZAU, but if your atty has recessed or near recessed + Pin in the 510 connector then you may have firing problems because of this lack of adjustability inherent in the Hippo's design.
A revised version of the Hippo is probably a good idea. One that supports an adjustable + Pin in the 510 connection & the proper tolerance of the mating piece to the provari would make this a slam dunk product.
I still give it 4 stars, primarily because 405 Vaperz helped me sort this out and we got it working. I recommend them highly and would do business with them again in the future. Besides that, the thing looks boss with a Hippo, Gemini and a Twins installed on my Blue Mini Provari and AC9.
