I never pay attention to the temperature lights.
I am pretty sure they are set up to stop blinking when the unit has met the exact temperature for whatever setting you are on but I agree with you, they seem a bit unreliable.
Since I care less about what exact temperature I am at and more about the clouds I am getting, I have dismissed this feature and quite frankly find the blinking lights a bit of an annoyance. This is one of those YMMV features if you ask me......
Don't get me wrong.....I would love to have more temp. settings (and they tell me that will be included sometime down the line, but not too soon). It's just that I really don't care if I am exactly on there as long as the unit is performing and producing good clouds.
As for your warranty question, Haze stands behind their product and the service has been no less than outstanding! I wouldn't worry about them taking care of you should you find the need.
I am not sure if they have a defined process of swapping units out but if you are worried about being without the unit and want a replacement shipped first I would just ask them for that. Ask for Jamie or Amy (there are only like six of them but they manage to provide great responsiveness to service questions). I have been working with Jamie and he/she (frankly not sure on the gender) has been extremely open and responsive.
@NickDlow had been working with Amy and seems to have had a positive experience ad well.
He had an issue and was able to get a new unit shipped before he sent his old one back. I had the same offer but not sure if this is a courtesy to us early adopters, decided on a case by case basis or something else......
Based on my experience you could offer the security of charging your credit card again if the original doesn't show up by an agreed upon date to get them to send you the replacement first. However I don't know if they would even require that.
Glad you are enjoying it!
It has been said time and time again that this unit is not for everyone. If they had more temp settings I think it would cater to a wider audience. However the unit (as is) offers great convenience features like the dual bowl, easy cleaning, removable batteries and the multipurpose cans (for wax/oil/herb on the go) which give it a big advantage (IMO) over a lot of the competition available on the market right now.
Come back and tell us more after you have had more time with it. I am interested in addition opinions and perspective on this.
