I have been using a prototype Motovac in my BMW motorcycle repair workshop. In the year I have been using the Motovac I have found it to be extremely easy to use , accurate and reliable. The built in rev counter is a great feature to ensure the carbs are balanced at the desired RPM. During this time I have had no issues with the product and the ease of use and portability make it a no - brainer for use when on the road as well as in the workshop. I have no problems recommending Motovac to anyone needing a simple to use but versatile vacuum gauge.

P.S.  I’ve just tried the Bluetooth sample model . I loved the previous model but this has taken it to another level and has everything I need ….. a bit of awesomeness .”
