Everything I've tested.

Samsung's first triple-camera phone, with an ultra wide lens he thinks would suit the S10, though overall camera quality is probably not th…

Techsource's pick for best budget phone under $300, chosen for its camera.

A crowdfunded smart case with a rear display that he showed as a prototype, without a clear verdict.

A heavy, uncomfortable chunk of silicone shaped like an ear that he finds ridiculous.

A polarising case that some people hate and others love, with Arun unsure who it is for.

Not a crazy case, but he really likes how slick it looks.

A ridiculous but impressive scratch-and-sniff fruit case that gets strong reactions from people.

A cleaning-fluid-bottle case he calls dumb and pointless, though eye-catching.

A standard-looking case that changes colour with heat, shown as a neat gimmick without a firm verdict.

An unlicensed Batman spinner case with a metal spinner that lifts the plastic, a nice touch overall.

An absurdly expensive limited-run titanium bumper, presented as crazy in price rather than judged.

A fidget toy that sticks to the back of a phone and impressed him more than most fidget toys.

He cannot understand the thinking behind the grass case, though it will make you stand out.

He hates how it looks but it is the softest, most comfortable case he has held, though it barely fits a pocket.

A battery-powered case with Nokia 3310 quality games that splits people into those who see the point and those who do not.

A supercar-themed plastic case that is not bad looking, with a fold-out stand, but not his thing.

A slim, light mobile controller with decent buttons but flat joysticks that don't feel great.

An extremely resistant case that floats, resists drops and prevents overheating, though the battery claim is the company's.

A glass cleaner that works surprisingly well on phones, removing fingerprints and leaving a silky finish.

A clever two-way clamp for using a phone alongside a laptop, as long as the laptop hinge is good.

His favourite smartphone printing accessory, working with no Wi-Fi, power or battery and giving vintage-looking prints.

An odd-looking elastic strap that works like a backpack for small items and is comfortable to hold.

A stretchy stick-on wallet with a fold-over flap that he would trust with cards and cash.

Not really a smart gadget, but an ornament with interesting augmented reality features.
