My sons gave me a Harbor Freight version at least 10 years ago, maybe 15... Still going strong. It's the cheap one, nothing fancy.
It wouldn't turn the diesel over in the Excursion I had, but when fully charged, it's turned everything else over. I used it recently to start my 300L when the battery was dead (my fault) and it worked great. The trick is to keep it charged so when you need it, it works. I often toss it in the trunk for long trips, especially if the car is going to be sitting at an airport or cruise dock for a week.
I was skeptical until I realized the pro tow truck drivers were using them, albeit a better version (not Harbor Freight)
Don't toss the cables though. The booster is good, but sometimes a car that is hard to start may drain the booster and you'll need the cables anyway.
