I bought the STRONGEST Tech Ever!

Well designed but didn't save the MacBook Air, which was dead after the drop.

Barely scratched and survived a 13.5 kg iron ball, showing real durability that justifies Apple's premium.

Scratch resistant until harder picks and survived the iron ball, but scratches more than the Ultra.

Feels solid for $90 and handled boiling water, but scratches easily and its software is not nice.

The original brick died in water and smashed in the drop, so its legend is overstated compared with the new XR21.

Marketed as unbreakable, but it was wrecked when used to tow a car, earning 4 out of 10.

Survived a 5 m drop and only failed at 10 m, which he called a very respectable 9 out of 10.

Sounds good and survived a 10 m concrete drop, a strong 9 out of 10.

Tear and water resistant, but the pages burn, so 6 out of 10.

They work underwater using radio waves, though sound quality is mediocre, earning 8 out of 10.

Survived being frozen with dry ice and a 50 mph car impact, scoring 10 out of 10 and later 9 out of 10 for the overall endurance.

Survived a soak in ginger ale where a normal card died, but cracked from the door slam, so tough but not invincible.

Tough and clever in design, but knocked over it stopped brewing and got damaged, so he gave it a 4.

Shrugged off water and a huge drop that wrecked the old 3310, earning 10 out of 10 for durability.

Shrugged off boiling coffee but was terrible for gaming and its trackball failed to a hammer, scoring 8 out of 10.

Underwhelming looking and not functional for normal people, as it burned, tore and gives no warmth or padding.

Extremely solid RC car that took a crash and acted as the impact vehicle, earning 9 out of 10.

Came through the drop with only a scratch, earning 10 out of 10 for outstanding construction.

Even in a case it was dead after the drop, showing the tech inside is vulnerable.

Protected an egg from a big drop, to his amazement.
