First the positives.  This feels really robust and well constructed.  Nice weight in the hand. I have very fine hair in a short bob and I wanted this for just flicking the ends under when my hair isn't behaving in the morning after sleeping, so not for everyday use and it works well at that.  Three temperatures, I use it on the lowest, with my average use time being 2-4minutes at a time (I actually measured this with the stopwatch on my phone). Now the negatives. I can only get 17 minutes use in total before it runs out from fully charged (again measured with my stopwatch). This was 8 uses and included warm up time.  Whether this is how it should work or mine is faulty, I don't know.  It does charge OK, but with only 17 minutes of charge it's unsuitable for any travel more than a few days, unless you're happy to take the charger with you.  The charger is quite bulky and you can't use the brush whilst it is charging, which is a big negative which how frequently it needs charging. Would give it 5 stars if it did last for 40 mins as advertised.

This hot brush also came faulty, and was on charge for hours and hours but just remained the red flashing light- had to return 

Great speedy delivery. Fab hot brush with a travel case. Purchased for travelling as they were a bargain in the sale.  I’ll be ordering more for presents before they sell out. 

Heard up really quickly and perfect for styling long front pieces of hair. I mainly use it for turning ends under and refreshing from bobble lines :-)

I tried over the past few days to get this device to charge and it just won't. The red light just keeps flashing.
