Chain coming off, is it really a common problem with chainsaws?

I have an EGO self-propelled mower and love it. I would love to buy an electric chainsaw but I see many reviews on Amazon with customers number one complaint that the chain comes off way too easy. Is this really that common or are experienced chain saw users that post these reviews not doing something right. I’m considering buying from Home Depot so I get to test drive the saw for 90 days but if this really occurs that often I don’t want to waste everyone’s time by returning a saw.

I used the 16” chainsaw to cut down and then cut up about a dozen large cedars on our lot. During that process I had the chain come off once, maybe twice, I don’t remember specifically.

1. That’s a fair amount of cutting. I didn’t feel like the chain was an issue.
2. I’m a novice user. This is my first chainsaw.
3. When the chain came off it was because I was struggling with the saw getting pinched, which may be something a more experienced user would have been able to avoid with better technique.

Overall I thought the saw performed very well.

I've used the 14" model and have also had the chain come off a few times. This appears to be due to the large knob which pinches the bar in place and locks the chain tensioner down vibrating loose over time. (Leading to the chain gradually losing tension, and then coming off when it gets pinched or knocked.)

It hasn't been a major problem for me, and after I got in the habit of giving that big knob a tightening twist every so often I haven't had it happen again. Once you understand how the chain tensioning system works (loosen the big knob, dial in the tension you want, tighten the big knob) it is easy to use and as long as you make sure to tighten the big knob down enough it doesn't loosen up too much with vibration.
