If the NTXr was so good why did it need replacing?
Cheaper price may mean cheaper components that don't work so well, not so good, or it may mean some cheap child sweat shop in the Middle East.
I like Delkim because they stick with the same alarm and don't constantly change it.
Part of the reason I will never change to a Fox alarm is because they keep changing the range every few years.
Next thing Delkim is a British family owned business, and the alarms are made in the UK, so as far as i'm concerned, Delkim are ahead by far.
