I purchased a set of led bulbs for my new 2020 backcountry from Sii and went to install them and one of the ears broke off while attempting to twist it in on one bulb. I contacted him and he was quick to respond with yes that's what happens when you don't line them up properly. I responded with my background as a mechanical engineer and told him he has insulted my ability to install a bulb and it's been several weeks and he has not responded back at all. It took at least twice the pressure to remove the skidoo bulb then I ever put on the tab that broke. He offered to invoice me for another one in his first response. Why would I give him another penny with customer service like he gave me.
