i used this bar in a crossfit gym setting (they have about 20). i was looking for reviews on it and found none so thought id chime in. i used the Mens 20kg Bright Zinc.
its a good general use bar. The knurl is somewhere between the Rogue 2.0 and Ohio bar. It's grippy but not overdone.
At the price point, i'd probably lean towards a Ohio bar but if you don't like the knurl this might be the bar for you.
for it being in the gym with multiple people using it day in and out, it looks to be holding up quite well (but i cant say the exact age of the bars)
