Suboptimal, but not many other options available to transfer articles from Android to Kindle. I reached my "sent limit" immediately after sending only one article, and there is no indication of when (if ever) that limit gets reset. Can I send one article per hour? Per day? Forever? The sending process is pretty cumbersome, but that's largely due to Kindle's infrastructure. The layout is simple, no frills, looks nice. Cannot uncheck all items. Article I sent looks great on Kindle app though.

Too many articles from multiple sources (WSJ, NYTIMES, LA Times in pro quest) resulting in truncated or zero data docs sent to Kindle. Appreciate the merge function and I paid for no ads at a very fair price. Just wish the docs sent actually captured entire articles. Very annoying to have return to the sites and resend with another app. That one works much better but of course, is much more expensive. But if STK doesn't improve, I may have to upgrade. Edited

As good as the amazon app on Win10. It doesn't do pdf's very well but the app makes it clear that it is designed for web pages and, frankly, the Amazon app doesn't do pdf well either. For web articles, the formatting on this is top notch; more often than not it is cleaner than the Amazon app.

Works sometimes. Not the best UX design, and not the most reliable.. even if you pay the full price. Since paying for the full experience of this app, i've learned that if you log into your Amazon account and find your kindle account in the settings, you can then find your "kindle email address". Once u have this, u can email that address anything from your email thats linked to Amazon & it goes straight to your kindle without the need for using this app. Haven't needed to use the app since.

I used to LOVE this, but... Anytime lately, when trying to use the app to send an Epub book or just any PDF, I'm told "the file is too large". I looked up the specs again, to see if something has changed, but nope! Nothing changed. Limit is still 50mb (which is an absolutely ridiculous low amount - heavy sigh), so WHY can I not send an Epub book at only 44.6mb?? Turns out I can't send it to my Kindle via my email, which is also a way that normally works!! What the freaking heck is going on???
