Is this the best wireless antenna booster

Have just found this and it looks amazing value for money (£30) but are there any other ones i should consider?

That one is 15db and hawkings outdoor aerials are 14db which apparently when operating between 2 14db aerials can cover a distance of 2 miles so should be powerful.

Was hoping to be able to point it at uni library which is about 300m away (across a meadow though)
