I can only give 4 stars. It works really well and is burglar-proof and does what it's supposed to, but when we reach the cold months with frost I couldn't get into my cargo area even though I had lubricated them with the included oil regularly. Unfortunately my heat gun was in the cargo area so I couldn't warm them up. So it was a sad day without being able to get into the cargo area 😞 Luckily I only had meetings that day. But the next day the temperatures came up and I was able to get in. This is a very annoying thing about the system. Otherwise they work😉 my neighbor's car was used up and mine was untouched 🤩
