Mixed experiences
I report mixed experiences. Nov 2016 Cubot Dinosaur 3GB/16GB Android 5 Via Amazon. Didn't work. Full refund. Dec 2016 Cubot Note S 2GB/16GB Android 6 via Amazon. Great. Still works OK today but OS now redundant. Mar 2019 Cubot X19 4GB/64GB Android 9 via Gearbest. Worked well but after 6 months developed a well known charging port fault. Refunded 75% from Gearbest not Cubot. Sept 2019 Cubot X20 Pro 6GB/128GB Android 9 via Gearbest. Great. My best ever phone, fast (no lag) with good storage. Still in daily use. So its a bit of a mixed bag. Cubot warranty is worthless in the real world because it's far too costly and time consuming to ship the faulty product to EU/Poland (where warranty work is carried out) or return to China. The best way to buy is on Amazon to benefit from their no quibble returns policy for faulty products in your home country otherwise you risk being left out of pocket with a DOA or part working phone. To summarise, Cubot do make good, cheap and reasonably reliable phones but you must choose your seller with care and don't rely on the Cubot warranty because China's a long, long way away.
