Slotted bedsheets - Massive pain in the ass to clean/change.

Lit up shower head - Nifty. Pointless, but nifty.

Phone steering wheel - Great until the game has buttons to push. Also, I feel a better wheel could be found.

Onion shaped napping aid - Good way to suffocate. Looks ridiculous.

Wine bottle with glass - Looks useless.

Gun leash - Clever, but a great way to get the cops called.

Chain clock - Brilliant!

Banana stand headphone holder - Brilliant!

Battery with charger built in - Would be nice if it didn't mean sacrificing at least 33% of your battery life to have it.

Wrist contraption - Does not exist. If it did, its still far to huge and clunky. Large unprotected screen area would be very prone to damage.

Arm pillow - Fails when arm is removed due to lack of central support.

Rubber band screw extractor trick - Not all that effective, but at least something to try. Proper screw extractors work better.

Pen bow - Eh.

Circuit board pick - not bad.

Bag of chips > bowl of chips - Not bad.

Zip tie ice chains - Pretty good, though I question how long it will last. -As pointed out below, would be extremely detrimental to braking. I change my opinion to 'Impractical and outright dangerous'.

How to fold the fitted sheet - Impressive as a mental exercise, but who folds sheets?

Fork/knife/spoon pen caps - Pointless. Saves little room over regular utensils. Combines two items that are in no way related.

Cheap gaming mat - Useful if on an extreme budget. Mouse pads are hardly expensive unless you buy something branded for some reason.

Bacon hot dog turtle - I fear the inside will be undercooked, and the outside overcooked. Also, meat overload.

Tea cup - Only useful if you fail to realize you can add more milk, and so can adjust it until its where you want.

Exercise bike mario cart - Not actually a new idea, just mixing the bike makers idea with reddit nostalgia.

Collapsible bong - Cleaning would be an issue, as would leaks. There are far handier methods for portable pot smoking.

Target alarm clock - Get more sleep so you wake up on time.

Beer Chess - Chess takes a long time, beer gets warm. Also, not a lot of crossover between people that want to play chess and people that want to drink up to 16 beers in one sitting.

Bottle cap bag sealer - Mangles the bag.

Sandwiches in bread bag - Not bad. Not great, but not bad.

Flashlight door handle - Piss poor design that has no strength. Put any torque on the handle and it will snap.

Extendable balcony - No method to open just the window. Unsightly when folded up. Increased complexity of the seals create a leak hazard. Undoubtedly costs more, and is less safe, than a permanent balcony would be.

Weird folding chair design - Doesn't actually fold up much. Wood is very heavy, that chair would weigh easily 2-3 times as much as a similar aluminum chair. Would tend to sag as it aged. I forsee huge issues with attaching the cloth to the wood.

Color matching pen - I'm curious how they plan to clean the head to prevent color contamination. Still, kinda nifty.

Extending coffee table - These things are cool. And have existed since LONG before reddit. Still, nice, and they should be standard.

Stacking USB cables - Genius!

Giraffe lamp - meh

Dude pulling his own plug night light - Very clever!

Key guiding lock - I might suggest drinking less.

Teapot stand - Looks like a great idea, especially for old folks with poor arm strength.

Pizza scissors - I'm not sure I want to admit that I eat enough pizza to think this is pretty cool...

Oreo dippers - If your fingers melt in milk you have more serious issues.

Finger guard for cutting vegetables - Could be good for the more clumsy among us.

Chop sticks with clothes pin spring - Just use a fork.

Lawn thing - Used up a huge amount of floor space for what is at best a single nice spot to sit.

Non foaming cups - Sacrifices a ton of stability to prevent the pourer from having to pick the cup up.

Spikey wall rack - Ok I guess. Just a standard pegboard with a non standard design.

Bed table end tables - Not bad, though requires a flat hardwood floor, and I forsee jamming issues. Also takes a very specific size of bed to function.

Door in a door in a door - Kids would love it. Not very structurally sound though.

Baby hooks for bathroom stalls - Seems functional enough. Most bathrooms have a handicap stall where you can park the stroller though.

Dust mop slippers - Seems slippery. Can't wear them outside. So wide they could be a trip hazard. Would attract psycho cat attacks.

Tea hangar - Trying too hard to be clever.

D cell shaped salt and pepper shakers - I approve

"Stop asking me how i did it" brand arm slings - Clever.

Toilet bowl shaped water dish - Grandmothers the world over would love this.

Chair thing - Kinda cute.

Condometric - Considering what the #1 insecurity among men is, I feel this product was not well thought out.

Keyboard lunch tray - Looks incredibly annoying.

Nokia phone - ???

Book laptop case - Nifty.

Car dealer code - May have been true some place.

Han solo ice cubes - Fun novelty item, but in the end its just ice. Also, very long and thin.. Considering how infrequently i can get square cubes out of the tray without cracking them, I think we'd be going through a lot of Hans. -Someone pointed out that the tray is silicon, which would greatly improve the odds of getting Han out intact.

Stalker seat cover - Useful for freaking people out.

Copy paste thingy - Ctr+C, Ctr+V

Butter slicer - Still doesn't address the issue of trying to spread cold butter onto bread.

Door as a computer desk - Laminated doors are not know for their strength. Good luck anchoring the feet to it.

Alternate method of hanging pants - I approve of this and would like to subscribe to your newsletter.

Female to female adaptor for the filling of small toothpaste tubes from large ones - Works I guess. Not sure if small tooth paste is so expensive that I'd bother.

A method for hiding your liquid lunch supplies at work - Very nice.

Page holder open device - Am I the only one who has never actually had this problem?

Drugs - While the ingredients may be the same, it must be cautioned that the pills still may not be. One may be time release and the other not, and other things of that nature.

Bookcase - I fear its design is going to make it not very ideal for the holding of actual books, and will become quite unreadable once full of books. The tetris bookcase is superior imo.

2L pour spouts - Never had much of an issue with the old fashioned method.

Cereal bowl - Not bad, though I'm one of the heathens that lets their cereal sit until its mush before eating.

Hot sauce spray nozzle - As it dries, it will tend to clog the nozzle.

Pancake pillows - Nice

Flying alarm clock - Again, get more sleep.

Sofa to bunk bed - Thats... Pretty damned brilliant, actually. Looks quite stable as well.

Odd 2 person rocking chair - Looks seriously annoying to get in and out of. 2 person nature locks it into that extreme reclining position.

Anti theft lunch bag - May not get stolen, but may get someone to throw it out.

Ipod walkman case - Pretty sweet, tbh.

Spaghetti measuring device - Weight is a better measure. This only works for a single type of noodle.

Cassette tape phone case - Not bad. Not bad at all.

Size 1,450 slipper - Pretty sure this was a publicity stunt.
