Amazon.com: Customer reviews: Impresa Products Concept 2 Rowing Machine Chain Oil - 4 Oz - Premium, Custom-Formulation for Exercise Rower Chains - Compatible with Model D and Other Major Brands - Made in USA
This product is critical for protecting my $900 investment in a rowing machine. The product arrived in a sealed bag to prevent leakage - there was none, but better safe than sorry. The chain oil is in a convenient bottle that is easy to use, and is a good viscosity. As a bicycle rider, I know the value of maintaining and protecting a chain.
Right after the 30 day return window closed on Amazon, the digital screen/interface has started showing an error message with no way of fixing the issue. Way too expensive of a machine to fail in less than 2 months.
