Brilliant thermometer and helpful customer service

I was pleasantly surprised by the superiority of this thermometer over previous ones I have owned. Comark is definitely a brand to look out for. I had also called the contact number on this website for some queries on the functioning of this thermometer and found the information given to be very useful!

Seems accurate but not quite what I had expected

The picture just shows the "head" of the thermometer. One of the reasons for buying this particular model was that it appeared so neat - something I could easily put in my pocket. I had not realised there was a long probe at the back of it.

Firstly great service - ordered on the Tue morning arrived Wed morning, not bad for the Highlands! The thermometer works very well for my use, which is open water swimming, Clear readout and waterproof which is key for me. Spare battery provided too which is handy. Would definitely recommend company to family and friends.
