It is a feature of the product, so I think what to point out as a fault, but one point to worry about. I feel troublesome opening before use. I think that it is convenient to have an easier method rather than cutting with a cutter or the like. As for price, it is very conscientious price, I want to use next time.
Automatic lubricator used oil type before. This time for the first time we can purchase the grease type cheaply (campaign price) and wearing it on the machine is running. I think that it is worth having a favorable product if it falls within the set period.
