Review title: Metal except for the silicon ring
Product review: The injector was great until the silicon ring broke making the injector useless. I called to get a replacement ring but the company said that they did not carry them and that they could not help me get one.I could not find a replacement elsewhere. So the extra money you pay for the metal injector is not worth it. A cheap plastic one would cost much less and last longer. Poor customer service.
