Heat added. Best price I've seen on this and I live in Hertfordshire! :D
Would hold out & see what Amazon brings to the table with their recent purchase of Ring before splashing out.
I saved up almost 2 years of paper rounds, washing cars and mowing lawns to get a DX4 100 mate, came with Wing Commander 3. Wiped the floor with your puny DX 66. (lol) (lol) And then came the pentium literally a month later which came on motherboards which were totally incompatible with the RAM, sound card and graphics card that my PC had (was it ISA or something?). The days when you could drop a grand on a PC and it'd be worth £200 in 3 months (lol) But yeah this door bell is vastly overrated. Their support who claims to be your neighbour is ok I guess, they tried to resolve my issues with the quality of the image but eventually started to ignore me. Probably because I told them what I thought of their product and their email blocked me 8)
You have to rent your doorbell nowadays?
You'll never improve on my knockers
