[3] Loz Etheridge of God Is in the TV called it "an album best experienced on the open road with the sound cranked up to the max".

[6] Jessica Goodman of The Line of Best Fit stated: "removed from the expansive instrument-led sounds of previous records Ganglion Reef and Golem, 1000 Days immerses inwards.

[8] Andrew Crowley of PopMatters found the album "a fine effort by Wand and well worth seeking out for those with a taste for garage rock not yet sated by releases this year from Mikal Cronin, Warm Soda and Thee Oh Sees".

[9] Paul Bullock of Under the Radar wrote: "1000 Days swings wildly from Black Sabbath-style paranoia to delicate Van Dyke Parks weirdness with an increasingly erudite command of garage rock while still managing to maintain much of the enigmatic charm of their previous releases".

wrote: "though the triumph of 1000 Days is its fusion of light and dark, there are some moments that feel out of place: the murky noise on instrumental "Dovetail" is a bit harrowing against the gentle acoustics on the title track, while "Little Dream", a 38-second spurt of woozy punk, appears and disappears out of nowhere".
