Honestly for the price these are solid. Bolted right up to my KTM and gave me just enough lift to stop my back from aching on longer trails.

snatched these up on sale and super happy with 'em. Much better than trying to dry off my leather glove every 5 mins!

I used this to replace the lines on my old Craftsman lawnmower and it worked perfectly. The 10-foot length is generous, giving me plenty of extra for future repairs or other small engines in the garage. It fits securely on the 1/4 inch fittings without leaking, and the wall thickness seems adequate for standard gas usage.

OMG these were a lifesaver for my daughters wedding reception! 100 candles for this price is insane and they lasted all night long without any duds. honestly better than buying the cheap ones at the dollar store that die in 2 hours. They give off a really cozy glow and i didn't have to worry about the venue's fire rules since they aren't real wax. Everyone was asking where I got them and I told them Amazon had the best deal for bulk. Totally worth the buy if you have a big event coming up and want that warm atmosphere without the mess of real candles.

Not bad, but keep in mind this isn't for court cases. If you need something for legal stuff, you gotta get a different version with a witness and all that. For just personal info though, it does the job.

I usually use the high-end stuff from Sephora, but I grabbed these for a wedding weekend and honestly they work just as well as the $20 mini cans. The hold is solid, though it's a bit sticky on the hands if you touch your hair right away. For the price, you really can't beat a 6-pack.
