This was one of the best installation type jobs I've had done; John was curteous, friendly, informative, gave unbiased assessment of the work, was always on time, always got on with the job, no mess, clean and tidy all the time within the constraints of the job, I would definitely ask John to do other work and in fact already have done; you can't get better work or workmanship than this, he didn't charge for work not done and even proviced a refund of some costs due to the bit of kit not being required - brilliant, highly recommended
