Description
Spearlab cryo foam dewars (EMS)These foam dewars are safer, longer lasting, and have better insulating characteristics than stainless or glass for a fraction of the cost. Foam dewars are insulated with fine closed cell foam, which is chemically inert and mechanically robust enough to withstand direct exposure to liquid nitrogen without leaking or deteriorating. In addition, because of their reduced thermal mass, foam containers produce less liquid nitrogen when filled and collect

It's a chunk of wood! Perfect.
Color: Black Walnut
It's a chunk of wood! Finish is great, height is great, looks great. Easy to clean unlike foam ones.
I did get one that was warped but the replacement was fine. Just check that it's actually flat when you get it

Decent product. Fits perfectly for 61/64 keys. Just slightly short for 68.
The finish seems fine for the piece I received. Didn't get any splinters or rough edges. Treated it with mineral oil overnight, it now touches and smells great. Just slightly too short for 68 layout but really can't complain for the price. Wish they offer more width options for TKL and full size as well.

Warped Wood
Color: Black Walnut
I know it's inexpensive, but regardless of the price of an item, it should do what it's meant to do somewhat effectively. The wood was warped and did not sit flat on my desk.

Great wrist rest, advertised dimensions slightly inaccurate.
Color: Black Walnut
Perhaps this is nitpicky but I purchased this wrist rest because it was perfectly sized to my keyboard at 29cm wide. It got here, and it's a fine wrist rest in terms of quality, material and feel, but it's not 29cm wide, it's 30.5cm wide. The other dimensions are accurate enough - both only .1mm off, but the mismatched width against my keyboard is enough for me to notice it and obsess over it. If that doesn't bother you, I say go for it. At $15 it's a good deal.
