With Wyatt Europe, I have a really good partner in after sales and application development/method development. The system is very flexible and with the service contract I always can count on immediate remote-help. Although, I am not very happy with the dictated combination of hardware and software developments meaning that I am somewhat dependend on expensive software-changes for optimal use of the hardware, and respective bug-fixes. As a university research institute we don't have the money to change working hardware, like in industrial settings. Wyatt US only provides online help if the instrumentation is not older than 10years, which means the possibility to satisfy customers like us is only possible by making a lot of effort. The free webinars offered to us during COVID19 were more than helpful, including the user seminars in the last weeks.
