[1][2] Outside of "Check", the two produced fellow Dreams Worth More Than Money track "Jump Out The Face"; their contributions differed from Mill's usual work with Jahlil Beats.

[4] Mill teased "Check" with a 15-second clip via Instagram on April 30, 2015, featuring Metro Boomin and fellow rapper Travis Scott.

[14] Writing for Consequence of Sound, Michael Madden picked the song as one of the best tracks on the album and called it a "head-rushe[r]" that is a "solo judder".

[16] At PopMatters, Joe Sweeney identified the song as a "relentless banger" showing "Meek in his element, rapping so hard" with heavy belief, when "even the instruments need to step off".

[12] Sweeney said the song has "a huge beat" alongside Mill creating a more orchestral feel than fellow album track "Lord Knows"; he also noted it is "more addictive" than the single "R.I.C.O.

[17] Tom Breihan of Stereogum wrote that Mill shows his level of "internal energy" to simply yell one word repeatedly and "make it sound like a completely powerful hook" on the song, while describing the production as providing "a tense and ominous backdrop to Meek's furious ranting".

labeled the song a "boom tune" that includes "brick-breaking beats, cautionary air raid sirens and other assorted sounds" in its production, while Mill is high energy on the "bands-stacking single".

[13] For HotNewHipHop, Kevin Goddard wrote that Mill demonstrates his lyrical abilities and provides "a catchy new baller's anthem for the streets".

[15] Elias Leight of The Fader branded it a "ferocious, imperious single" that is "bruising and low-slung", succeeding with a similar combination of "placid piano" and "booming bass" as rapper Future's 2015 songs "Trap Niggas" and "Fuck Up Some Commas".

[1] XXL's Aicha Jesal called the song a "club banger", seeing it as a "turn up track that makes you want to get crunk" like much of Mill's other work.

[6] Jesal 'Jay Soul' Padania from RapReviews saw the song as of a higher quality than earlier tracks on Dreams Worth More Than Money, such as "Ambitionz" and "Pullin' Up", and thought it would be quite appropriate as an album opener.

[25][26] According to reports from the city,[27] a fight broke out on the set and a man was pistol whipped during an altercation between Mill and fellow rapper Louie V Gutta's crews.
