Treatment was enjoyable although I expected to sweat more! They suggested I start on 8 for my first time and go higher the next appointment, but if you enjoy laying in the sun on holiday I suggest you ask them to turn it up to 9 or 10 from the off - you’ll be able to handle it easily :)
I am a regular and their service is quick and good! However, I don’t like that they move around your appointment time, so you need to keep an eye on the appointment time or you may find it’s significantly different.
