Hi everyone,
First post here. I purchased the Iolite unit after reading the reviews here. In hindsight, I wish I hadn't.
While I have not had any Issues with the mouth piece, I do think the mouthpiece (and the entire unit for that matter) is poorly designed. My screen with the holes in it fell out of mine, couldn't get the retaining clip back in and in the end just put a plain ol' small screen in it. It worked fine. For a while.
After a couple of weeks the unit became increasingly difficult to get started. While I started using Ronson in the unit, after just several uses, I switched to Blazer and Vector butane.
Despite changing butane brand, eventually the unit would not start anymore. So less than a month after purchasing it, I had no choice but to mail it to Ireland at a cost of a bit over $30 (with insurance).
I mailed the unit on the 15th and Iolite notified me that they received the unit on the 22nd. As of yesterday they informed me that their engineer has not yet looked at it because "we are extremely busy at the moment and would like to thank you for your patience and understanding."
WTF? Obviously they have so many returns that they cannot look at a unit they've had for over a week! Well, when you sell what is IMO a poorly designed product guess what happens? You get a lot of call to your service department.
While a cool idea and neat when it worked, my experience with the Iolite has been a poor one. I would not recommend it at this point. I would however recommend the Launch Box I purchased while waiting for my Iolite to come back. Nice to have a portable that actually works.
