BB making a very very faint creek

As the title says I can hear a very very slight creek every time I pedal in every gear, I am no expert in bikes but I think it could be the bottom bracket.
The Brand of BB is FSA Mega Exo (BSA) 73mm
I’ve looked on chain reaction and these are really cheap to buy but the reviews on these BB are awful.
Is it worth regressing the BB and reinstall??
or is it best to buy a new one and if so is there a better BB to get instead of the the same old rubbish.
The bike is a Vitus Sommet Deore.

    If they are that cheap then worth replacing surely? You could also see if anyone does a conversion to something a bit better quality?

    what size is the crank axle?

    If its 24mm just fit a new shimano xt bottom bracket.

    Are you sure it’s the B.B. that’s creaking? Creaks ‘from the B.B.’ are rarely actually from the B.B. in my experience. Check and lube the seat rails, Q.R. Skewers / thru axles, and pedals. Check the spoke tensions, and look for rim damage. Then give the chain a thorough clean, check and relube ( look for links that are coming apart, or pringling) when all that is done, if it’s still creaking, get a new B.B.

    or could be things like chain ring bolts, these can and do creak occasionally.
