1st problem not connecting to my solar panels for readings, quite important !! I, terrible communication, promise of technical contacting me, week later still nothing, went back to original salesman to sort, now need booster, extra money and even charged postage. Other neighbours experienced the same. I wish I had not left Sky, although more costly did sort problems and ring back. I was told technical very busy, obviously having lots of problems, bit of a worry!! Made a complaint and I was told I would hear from someone but guess what 3 days later nothing. Please beware if you get problems they are definitely one of the worst to deal with.
