Thanks for your quick reply! 200 C will be completely fine for our application. I think this part will work perfectly, and I plan to order it through your website. I haven’t ordered from your company before, but I’m really impressed by your quick customer service. Thanks again for your help.

Wes

I would like to inform you that we have received the divided vacuum chamber in good condition. We are impressed by the quality of the goods delivered and the care with which the VAT was produced.

Marc

I received your package yesterday morning (earlier than expected) and everything was perfect. I just wanted to say how much I appreciated your quick delivery and that you gave us that free gear. This was the first time we ordered from you, but it will certainly not be our last!

Alex

Vielen Dank für Ihre schnelle Antwort! 200 C ist für unsere Anwendung völlig in Ordnung. Ich denke, dieses Teil wird perfekt funktionieren, und ich habe vor, es über Ihre Website zu bestellen. Ich habe noch nie bei Ihrem Unternehmen bestellt, aber ich bin wirklich beeindruckt von Ihrem schnellen Kundenservice. Nochmals vielen Dank für Ihre Hilfe.

Wes

Ich möchte Ihnen mitteilen, dass wir die geteilte Vakuumkammer in gutem Zustand erhalten haben. Wir sind beeindruckt von der Qualität der gelieferten Ware und der Sorgfalt, mit der die Mehrwertsteuer hergestellt wurde.

Marc

Ich habe Ihr Paket gestern Morgen erhalten (früher als erwartet) und alles war perfekt. Ich wollte nur sagen, wie sehr ich Ihre schnelle Lieferung zu schätzen weiß und dass Sie uns die Ausrüstung kostenlos zur Verfügung gestellt haben. Dies war das erste Mal, dass wir bei Ihnen bestellt haben, aber es wird sicher nicht das letzte Mal sein!
