I used the Jelly 2 for several months and the Atom L for 2+ years. The hardware and base software is very solid, with some minor exceptions that can be expected for a small manufacturer.
The Jelly 2 was too small for me and the fingerprint sensor and camera were sub par. But if you want a tiny phone, its 100 times better than anything on the market. Get the Jelly star for the updates specs though.
The Atom L(and XL) was a solid phone, literally and rhetorically. The camera wasn’t flagship class, but solid. I never had a problem with performance, and the phone is very durable. Mine developed a connection issue which was annoying, but not a show stopper. Unfortunately, they haven’t updated this device any longer and there is no new version.
If you have any questions let me know.
This another factor why kids lean to iphone. Their parents buy them the shitty $100 android phone from the carrier store. Compared to a $1000 iPhone, it sucks pretty bad.
