    I give it 4 stars, just because of the price. If you want a neat, simple, and easy to implement solution to prevent sparks when connecting your inverter, this is what you want. It will certainly help prolong your contactor life. It probably costs them less than $10 to manufacture, so the price is a bit much. It does what it says it will do, it does it reliably, and looks much neater than a low cost solution you can put together yourself, so I still recommend it.
