I've been using SRAM 850 or 1051 chains on my bikes and I've had no complaints, but this Shimano chain feels so much smoother and quieter. I don't think I'll go back (even though using pins to connect the chain together feels less practical than 'master links'.)
Always use Shimano for the timing chain for a tandem bicycle...so it takes almost two chains to do the job. Always use their pin to connect the two chains and a quick like to finish the loop. Never any problems until it is again time to replace.
