My wife and I love our Blade X Max phones. We upgraded to it because of it's 32GB of RAM, 2.0 GB of ROM and 1.4Ghz Octa-core processor (yes, 8-cores). The Bonus that we really liked after we got it is how fast it charges on it's Type-C USB charging cord. oh and having a finger-print sensor is so cool and convenient, I don't know how I got along without it before.
But the one thing that made me go for it was the fact that when you stick in a micro SD-card (up to 128GB), it asks if you want to format it as internal memory. Both of our phones now have 160GB (32 internal + 128 SD card) of internal memory per the "settings" screen.
A few things I'm annoyed (but not frustrated) by is: 1. The Wi-Fi at work needs to be manually reset for the "I agree" screen to pop up in order to connect to the internet every single time. 2. The 6.0-inch screen is a bit big, making it difficult to operate with one hand though I've never turned on it's "one-handed operation" function, yet. 3. The camera could be better for a phone of this capacity but much better than what I've had on past phones. 4. the battery is not removable. If the battery ever dies, you can't just replace the battery, you'll have to get a new phone.
One time, my phone wouldn't turn on (never happened to the wife's phone). It was within 2 weeks of purchasing it. After work, I was gonna take it to the Cricket store (where I bought it) and see if they could fix it but I decided to try to turn it on again and guess what? It turned on and worked just fine. Been working fine since. I told the Cricket saleswoman about it and she said that some apps do that to a phone, so maybe it's not the phone's fault after all.
All-in-all, we really enjoy and love the phone, the best one I've ever used, to date and for <150 USD, it's a no-brainer. We've had the phone since Sept 2016 so we're still learning new, cool things about it.
