Software development required

This is a good product, but the lack of good software makes it impossible to use. The app is very bad. Don't buy it unless you want to develop your own application.

Pros
  • Special offer
Cons
  • Hard to say

Works but instructions are annoying

The instructions for installing the app were far from perfect. But once it's up and running, it seems to work fine. The circuitry inside is terrible.

Pros
  • Handy thing
Cons
  • Low maintainability

Do you call it an app?

Working. That's all I can say. But don't expect much, especially with the iOS app. Where is the timer function? Where's the security? How about custom labels? How about synchronized contact closure or custom slow control in 100ms increments from 100 to 5000? Sad.

Pros
  • Done
Cons
  • Some problems

Great DIY products

Everything I've read about the company makes this product good. Unfortunately, when I received my item from them, it was a dud. The return process was very quick and I received my refund within a few days. Normally I'd just ask for a new one, but I ended up making my own using an Arduino I had lying around.

Pros
  • New
Cons
  • Slightly torn
