I'm using the travel Ego and must say that. for me, it's the best hairdryer I've used for a long time - both from the weight and ease of use point of view and the results.
The nozzle constantly annoys me as it keeps blowing off, but I can live with it. For the time being.
My friend has just bought a Dyson dryer - I think her friend count doubled overnight and there's an official queue to try it out - but as her "special" friend, I got in the VIP entrance! I had a good play with it while drying my hair and am now starting a savings fund for one!
It's lighter than my old salon (though a lot heavier than my tiny Trip). The balance is amazing and makes it easy for me to use my dodgy arm. The nozzle can rotate to any position (helpful if you're as hamfisted as me when drying), and is simple to change, even when in use and hot. It didn't fry my hair, but made it softer and shinier than normal (and I don't usually get on with ionics). It also dried quicker than any other hairdryer I've tried (including other friends' salon dryers or the newest one that one of us has, the Q3-I think). Best of all, we could have a normal volume chat while I was playing.
I was surprised to find it's only 1400 watts (I think). Very powerful for that. It blows (literally) my old (but newish) 2200 watt dryer out of the competition. It's obviously not going to save me mega amounts on my electric bill, but with the time cut and the wattage cut, I will save a bit. Having said that, by the time I save enough for it it'll probably be an updated version that runs on fresh air or something!
