What it actually does
Three things, and it’s worth separating them because different people care about different ones.
It makes phone games playable properly. Anything designed with controller support — and that’s a lot now, including big console games that have come to phones — goes from awkward touchscreen taps to a real control scheme. If someone plays games on their phone at all, this is a straightforward upgrade.
It makes game streaming genuinely good. This is the part most gift buyers don’t know about and the reason enthusiasts rate it so highly. Xbox Game Pass, PlayStation Remote Play and similar services let someone play console-quality games through their phone, using either a subscription’s cloud servers or their own console at home. Those services are frustrating on a touchscreen and excellent with a controller. If your person has Game Pass, this pairs with it perfectly.
It’s portable in a way a console isn’t. It folds down to something that goes in a coat pocket or a bag. For commuters, travelers and anyone who spends time waiting around, that’s the whole appeal.
The connector: the one thing you must get right
The Backbone One plugs into the phone’s charging port, so it is sold in different versions for different ports. Modern iPhones and essentially all Android phones use USB-C; older iPhones used Lightning. Buying the wrong one gives you a controller that cannot physically attach to their phone.
If you can find out what cable they charge their phone with, you have your answer. If you can’t — and asking is a bigger spoiler than usual here, because there aren’t many gifts that require knowing someone’s phone model — then this is a gift to skip. A wrong-connector Backbone is not salvageable with an adapter you can pick up locally, and the returns process will take the shine off the occasion.
One further practical note: a thick phone case usually has to come off to fit the phone in. Most owners simply live with that, but it’s worth knowing if the recipient is someone with an armored case they never remove.
Who this is a great gift for
A commuter. The single best case. Forty minutes on a train becomes something to look forward to.
Someone with a Game Pass or PlayStation Plus subscription. They already own the games; this unlocks playing them away from the television.
A student. Small living space, phone always in hand, and no room for a second setup. It’s one of the picks on our college students list for exactly that reason.
Someone who plays a lot of phone games already. They’ve demonstrated the behavior; this improves it.
Who should get something else
Someone who doesn’t play games on their phone. This is a common misfire — it’s such a neat object that people buy it for gamers generally, and a person who plays exclusively on a console at home will use it twice. It is an accessory for an existing habit, not a way to start a new one.
Also skip it for a young child (the phone dependency makes it awkward) and for anyone whose phone battery is already a daily anxiety, because playing games through the phone drains it quickly. There is a pass-through charging port on the controller, which helps, but it needs a cable and a socket to be useful.
Is it worth it as a present?
For the right person, this is one of the most memorable gifts on the site — it’s novel, it’s genuinely well made, and it changes how they use something they already carry everywhere. For the wrong person it’s a clever object in a drawer.
The deciding question isn’t “do they like games?”. It’s “do they already play on their phone, or would they, given a better way to?” If you can answer yes with confidence, buy it — after you’ve checked the charging port.
