Power Blocks

I am very interested in purchasing a set of power blocks.My question is has anyone who’s owned a pair for some time tell me what maitnance is required,and what if anything needs replacing.According to them they last forever with no problems.If this is true it’s the first product of it’s kind.
Thanks,
Lou

I have a set of 5-85 w. bench and dip stand…had them for almost 8 years now and they still work great…a super investment.

Over 2 years and no maintenance. The only item that can get worn is the plastic retainer on the weight selector and that is not likely if used correctly.

Same here man - I’ve had mine for 5 years now and have had NO maintenance…save for tightening the handles with an allen wrench once. Great investment.
