AliExpress 3 items from $1.99 is a really good deal (via the app). Total is around $6.80 approx.
I've bought a scissors, wallets, Wii HDMIs, flashlights, LED digital clocks, and I have no reason to complain!
Most recent one included: 1x Stainless Steel Scissor, 1x LED Digital Clock (yes, it has 12hr, not just military time format
), and 1x USB Rechargeable Headlight (so I can use my hands if I need).
People tend to think "because it's cheap then it's crap," but paying more doesn't guarantee you better or higher quality. Almost everything is made in China so if you can get good deals on stuff you need, then go for it.
I don't buy just because it's cheap, rather it'll come in handy sooner or later.
Oh yes, gotta buy those metal sticks to find/detect water!
