Blu Studio One review

Dave Farquhar Android , , , , , , ,

I needed a phone in a hurry the other day when my wife’s Moto E started acting up. We turned to the Blu Studio One, specifically model# S0110UU. This is my Blu Studio One review.

It’s an inexpensive midrange phone for people who want to bring their own to their carrier rather than (over)paying on a monthly installment plan. It works with GSM providers like T-Mobile and AT&T.

What oil do I like? The person brought up Marvel Mystery Oil. I do like Marvel Mystery Oil inside the mower. But I think it’s too expensive for the deck.

Does HTTPS matter? Yes. Here’s why.

“Does HTTPS matter?” a friend of a friend asked. “I heard it does. Is that still true?” Yes, yes, and yes. Here’s why.
