ZaggKeys Pro Plus: If you have one, does yours work?

[teepeeayy]

I bought the ZaggKeys Pro Plus external bluetooth keyboard for my iPad. So far I'm really disappointed. When I type in Noteshelf, it repeats letters, misspelling a quarter of the words I type. I wrote Zagg, they said "charge it fully". Tried that. I even tried Notability just to see if it was the app. Same deal.

What is everyone else's experience?
