My experiences:
Good:
Band Saw - Item #93762 - works great, but the blades that HF sells (and the one that comes on it when bought) wear down quickly, just have to upgrade to a name-brand blade when the HF one takes a dump. Cuts quietly and accurately and I paid about $150 for it new, with a coupon.
4.5" flap discs for angle grinder - Item #68325 - work great, last as long as name-brand discs for about half the price.
Jackstands
20 ton Shop Press - Item #32879 - works well, but I hear the factory cast-iron arbor plates can break violently if put under too much pressure.
Ratchet adaptor set - Item #67925 - inexpensive and work well, I have used them with 1/2" IR impact gun and they have not broken.
Small Power inverter - Item #66817 - works well, have run drill with it and air mattress pump. it has interchangable terminal clips (for a battery, have inflated mattress off of four wheeler battery before) and a cigarette plug adaptor too.
Paper towel holder - Item #67700 - i use the crap out of blue-shop-towels and this is awesome for that. good strong magnets and simple design.
14" cutoff saw - Item #68104 - my dad has had a HF cutoff saw for about 13 years and it is still going strong. zero maintenance and zero part replacement other than abrasive blades.
Vice grips - all have worked well
pliers
screwdrivers - I bought the 22 piece set and have not ever broken or ruined any handles or tips. maybe I've just had good luck with them but I use them a lot. Item # 95114
Self-darkening welding helmet - Item # 46092 - works well, wish it had a bigger lens. but the head adjuster has not broke and I still use this helmet. (hoping to upgrade to miller soon though for a larger lens)
1" impact wrench - Item # 67096 - we use this at work to take off the dump-truck tires. sure beats a breaker bar with a cheater. only complaint is the trigger valve is in a stupid place.
The Okay:
Sand blaster cabinet - Item # 93608 - Works okay with right compressor, I've done a lot to try to take control of the moisture issue in my sandblasting but I still get clog problems ever once in a while. Also the window got kinda foggy quickly and is kinda hard to see through.
Sand blaster pressure pot - Item #34202 - again works okay with the right compressor, but it made a mess of sand wherever you blast and didnt allow you to re-use blast-media. works better with the deadman valve Item #92189. I actually don't ever use this one anymore and would sell the blaster for $10 if anyone is interested.
Tri-fold aluminum ramp - worked well for maybe 2 years and then the rivets that hold the support arms (the part that rests on the tailgate or trailer) wobbled out and came off. replaced HF ramps with aluminum ramps from Cabelas and I actually paid less for the Cabelas ramps and the Cabelas ramps seem like a better product. But I was still happy with my HF ramps, I used the crap out of them. Item #90018
dirtbike stand - Item #66552 - I think I paid $17 for it after a coupon, worked okay, but it still left the dirtbike kinda wobbly because it didnt have a large surface area, and the safety-pin design (to keep the bike lifted) gets lost easily.
Angle finder - Item #34214 - seems accurate but the magnet isnt the strongest. falls off metal objects easily. Upgraded to Husky Magnetic Digital Level from Home depot and never looked back.
Tool Box - Item #67421 - i use it. not anywhere big enough for all my tools. wish I had ball-bearing drawers. good beginner tool-box.
The bad:
Wrench set - Item #47467 - broke a bunch of the open end wrenches. cheap metal, doesn't like a lot of force. comes in cheap plastic roll.
Air compressor hose - the 50' hose I bought dry-rotted and cracked really quickly, within 2 or 3 months of purchase.
"tube benders" - my buddy had one and tried to do some tube work but it kinked almost all the bends and made the ones that didnt kink look like poo.
Fiberglass welding blanket - burnt through with even the smallest slag drops on first use. didnt protect what I was trying to protect.
