I have used and been around many auger types. Currently own a old jiffy legend which I love and will never get rid of and have a ION with the reverse that is a dream in the house with no fumes and it's quite. Love the ION for in the house the reverse works good but your still going to need an ice scoop some ice will float up your other holes ( And you will have to reclean your holes again) but great product. Think I've owned it three years now love it for the house and quick fishing trips( DONT plan on it lasting if you pop lots of holes). You need to have sharp blades for your ION other wise that's when you get people pushing down on them and it can be a workout (prally got 200-300 . ONLY bad thing I've had is need to charge battery properly. Had it arc on me and had to get another charger. Been a pretty spendy unit !!!
Looked at a strikmaster electric. I got to be a little more jealouse about it. Liked how it would spin faster while drilling. Just seemed better.
Seen and used the jiffy propane augers in action and wow there amazing. Always started up quick in the cold even when left in the pack of the truck on a cold day ( have had a few trips go bad real quick cause the gas auger wouldn't start). I have been looking at the pro 4 to run around on the ice just a few more pounds heavier but than your not worried about all the electrical with water and buying batteries and charging batteries. Just a 1lb bottle of propane can last awhile. WAY longer than I would have ever thought. When it did die using that 1lb bottle I was able to just hook up the hose from the propane tank for the heater.
But this the k drill seems to be pretty neat wish I seen one in action (or just had one). I'm sure it's super light. Just would like to see a couple videos of maybe one with a 8in and a 6in and see the difference in speed and what the difference in hole numbers would be. Be nice to see another video with different drill brands like Milwaukee ,DuWalt ,
