I bought this for a long haul flight and tested it out before while reading in bed (got the idea from the reviews here and have never thought about this before). It is lightweight, fits easily into the hand luggage, extremely comfortable, very soft. It does not irritate like the inflatable ones yet has only marginally more weight. Reading is a bliss and you wake up refreshed.
However.. for long term (reading in bed) use it is maybe a bit too cheap,too pliable,so I treated myself to the Tempur Transit, which is 5 classes better (alas,10 times more expensive, but in my opinion not really suitable for flights due to its weight and bulk).
But since this is a travel pillow it go 5 stars. Dont bother with inflatable ones, you will regret it.You will not regret buying this one.
