    • Great Value and Easy to Set Up
Color: Champagne Gold
I bought this as a replacement for my old phone after I lost it, and it has been a great choice. It was easy to set up, and I was able to recover my data from my cloud backup without any trouble. The phone looks great, feels well made, and is surprisingly fast for the price. I mainly use it for texting, calls, and browsing the internet, and it handles everything smoothly. I also appreciated that it came with lots of accessories, which made it feel like an even better value. If you're looking for a good-looking, dependable phone at a great price, I would definitely recommend it. ... show more

    • Good Bang for your Buck
Color: Champagne Gold
Didn't expect much for under $100 but this one's held up well. Screen is big and surprisingly smooth. Battery easily lasts me a full day, sometimes more. Storage is plenty, and there's a microSD slot if you need extra. Camera's decent in daylight, nothing special in low light, but that's expected at this price. Fingerprint unlock is quick and reliable. Comes with a case, screen protector, charger, and earphones in the box, which was a nice bonus. ... show more

    • 1/5 TONS OF BLOATWARE
Color: Purple
When booting the phone and finishing the setup, it immediately installed 71 APPS, random games, news, social medias etc. and after going through all of them and deleting them all. THEY SLOWLY JUST REDOWNLOAD back onto the phone...flooded with bloatware and sketchy that it just resinstalls the bloatware apps over and over. Kind of unsafe, not satisfied with the purchase. Only thing good about it is that it turns on and works but not happy about all these shady apps. ... show more

I recently got this phone and loved how easy it was set. I love how easy it was to connect to all my Google accounts and I have everything in one place. It was easy to set up my sim and all my apps, the phone is user friendly. I'm a sucker for anything pink so being able to get a pink phone was truly the cherry on top of this purchase. I use the phone mostly for work; checking emails, taking photos, and everything works really well! ... show more

    • Great backup phone for me!
Color: Champagne Gold
I was surprised. This phone replaced my Blu G91, it is 5 years old and still works fine. The new phone was cheaper and I didn't expect much. The big gain was going from android 10 to 15. Google had started complaining telling me to update my system on the old phone. Plus - K12 is a little faster than G91 K12 has a bigger display. Both have 128 GB and accept another 128 GB SD card. K12 has aptX, no where was that stated, showed up when I paired with some sennheisers. Pixel watch transferred easily. K12 had a little better wifi (ac) and better Bluetooth (5) but both a rev back from current. Minus - Lots of bloatware auto installed from Blu, disabled that. Some bloatware from Google but you can uninstall it. Have to disable the bloatware install with every system update. Defaults to 3D sound on Bluetooth or wire, had to turn that off every time. K12 has same size battery as G91 My use for the phone is mostly texting and music streaming. I use red pocket for carrier, $45 a year. I run the phone in the car for deezer, spotify and siriusxm. I use less than 500 mb a month on cell, my plans limit, but that is why it is $45 a year. Most of the time it is home on wifi using Google voice for texting and calls. Updated the op system and then moved the Sim card, pretty simple, working fine. The K12 is a good emergency phone, like my G91. Very pleased. BLU makes a reasonably priced phone that actually works. Battery lasts a few days. My 3rd Blu phone. I'll get a 4th in another 5 years.. ... show more

    • Study in opposits
Color: Champagne Gold
When I went looking for a new phone, I wanted just that, a phone. - - - - - - This one is an entertainment center. - - - - - - If you want all of the "social media", this either has it pre loaded or they provide a link to get it. I want a PHONE, that also does text, send/receive files, and (side note) takes pictures. This one is very good at those functions! - - - - My problem is all of the "stuff" that they have added, based on Google, that you CAN NOT get rid of! - - Read that again: you CAN NOT get most of the "stuff" from Google, off your PHONE! I spent hours attempting to clean off the items I do not want. MOST of those CAN NOT be erased or blocked. - - They get in your way as you try to place a call, or make a text. - - That said, if you want an entertainment center, with continuous, IN YOUR FACE news, weather, and "celebrity" displays. you will doubtless enjoy this one. - - Mine is going back! Please remember, the base phone is EXCELLENT! - - In light of the cost, it is phenomenal! It is just the garbage from Google that is the/my problem. ... show more
