Hardware & logistics
The borrowed clicker is a stranger you meet on stage.
Someone hands you the house remote seconds before you go on. You don't know its battery level, its button layout, or what its little USB dongle actually is. All three become your problem the moment the lights come up.

Backstage at a conference, the AV tech presses a small plastic clicker into your hand. It's meant to help. But you've now inherited three unknowns — is the battery about to die, which button goes back, and what is that USB receiver plugged into the presentation laptop — and you'll discover the answers live, in front of a few hundred people.
✕ The myth
"A clicker's a clicker — just take the one they offer."
They all do the same thing; no reason to bring your own.
✓ The reality
Three unknowns, one stage.
Unknown battery, unknown button mapping, and an unvetted USB device — and USB human-interface-device injection (BadUSB) is a real attack class.1
Most of the pain is mundane: a dying battery that skips slides, or a reversed next/back that has you fumbling on slide two. But the receiver deserves a mention too — a USB device can pretend to be a keyboard and type commands, the essence of the BadUSB class of attacks demonstrated publicly in 2014.1 On a shared conference laptop that receiver is just... trusted, because the last speaker trusted it too.
Bring your own — and you already have
The fix isn't to carry yet another gadget. It's to advance your own slides from a device you already trust and already understand: your phone. You know its battery, you know its controls, and it isn't plugging an unknown dongle into anyone's laptop. The clicker was solving "let me move slides from where I'm standing" — and your phone solves that without inheriting a single stranger's unknowns.
Battery
You know your phone's charge; you don't know the house clicker's.
Mapping
No mystery button layout to learn on slide two.
BadUSB
A USB receiver can impersonate a keyboard — a real, demonstrated attack class.

⚖ The honest bit — most clickers are perfectly innocent
The security risk is small; the practical one isn't.
Let's keep proportion. The overwhelming majority of house clickers are exactly what they look like — a harmless remote with a flat battery at worst — and a targeted BadUSB attack via a conference clicker would be exotic. So don't refuse one in a panic. The everyday reason to prefer your own is reliability: no dead battery, no reversed buttons, no unfamiliar feel. The security reason is a smaller, real-but-rare bonus. If you know and trust the venue's kit, borrowing is fine; when you don't, your phone is the lower-variance choice.
Where SyncBy!App fits
With SyncBy your phone is the remote — you advance the slides you're presenting straight from it, with no separate clicker to borrow and no USB receiver to plug into the house laptop. You control the deck from a device whose battery and buttons you already know. If a venue's own clicker is familiar and you like it, use it; when it's an unknown handed to you at the last second, your phone sidesteps all three unknowns at once.
TL;DR
- A borrowed clicker brings three unknowns: battery, button mapping, and an unvetted USB receiver.
- USB HID injection (BadUSB) is a real, demonstrated attack class — small risk, but real.1
- Advancing slides from your own phone removes all three.
- Honest caveat: most clickers are harmless — the everyday win is reliability, not spy-thriller security.
