Dear Mr. Mirco Beutler,

Writing this letter is to provide you feedback about "Temptrak system".

It has indeed upgraded our system of temperature monitoring and day-to-dayHygiene requirements and also adding value towards our vision for environmentalsustainability.

We appreciate that you were on hand to assist with the various challenges we facedand w,eJeok forward to your continued assistance in future.
