After my call, I was promptly given an appointment that exactly matched my schedule. The visit was very professional and relaxed, without any time pressure, and Mr. Spenner offered very good advice. The quotation was prepared quickly and the installation date was agreed promptly. Mr. Spenner was always reliable and the installation was done exactly on time. The whole experience was very pleasant and I would recommend Mr. Spenner for future projects without hesitation. Thank you for the great work and keep up the good work!

I can't say anything about accessibility by public transport, parking facilities and business premises, but I can only recommend Sicherheitstechnik Spenner. Everything was really perfect. I called and got an appointment straight away. The appointment was punctual, well organized, without time pressure and very good advice. I immediately received a quote and a possible installation date as soon as possible. Mr. Spenner was punctual, very nice and the appointment was kept. It was a very pleasant working relationship. For a possible next project, he would certainly be the first address. Many thanks and "keep up the good work".

We had first gathered extensive information about security technology in private houses and then also received a consultation and presentation from Mr. Spenner. We found the concept, the technology, the operation and also the price to be absolutely appropriate and reasonable, which is why we decided with great conviction to recommend Mr. Spenner.
The system was then delivered and installed within the agreed schedule.
We are very satisfied and can recommend the company Spenner at any time.

Mr. Spenner gave us comprehensive advice and patiently answered all our questions until we understood everything. The system fits our needs. The execution was perfect after consultation. We appreciate the friendliness, competence and reliability of Mr. Spenner. The alarm system was installed only yesterday - so we still lack some experience. However, we know that we can still call Mr. Spenner and that he will be available for any queries. If you want to invest in security, you are definitely in good hands with Mr. Spenner! We would like to take this opportunity to thank him for his efforts and his work.

Due to very positive experiences with the installation of our first alarm system ten years ago, we also turned to Mr. Spenner again for the installation of our new system. In addition to the intensive and individual consultation, we particularly appreciate the professional and timely installation, including the final personal briefing. Even in case of questions arising later, Mr. Spenner is & was really available and responsive at any time, even at short notice, and gave/gives the desired information at short notice! Thank you very much!

Mr. Spenner has installed a comprehensive Daitem D22 in our house, including outdoor detectors and security service connection. He was available for consultation and various follow-up questions at any time, even in the evening, and clarified every question very well. Extra services such as painting were possible without any problems, professionally and at a reasonable price. The installation date was kept on time, the installation was as usual professional, friendly and clean. We feel that we are in very good hands with Mr. Spenner and recommend him without reservation.

The advice was targeted. Mr. Spenner had all the components with him so that we could touch them. He advised us against components that would have generated more sales for him but were of relatively little use to us. That is always a good sign. We received the offer during the course of the meeting.
The execution was already a week later. Mr. Spenner worked extremely cleanly with very good tools. Just one small example: Overshoes. No drilling dust.
Mr. Spenner took a lot of time in the instruction and was not impressed by a bad-tempered child.
The alarm system is convenient and easy to use and expandable. It talks. It looks good. The siren is very loud. That's the purpose of the exercise.
Mr. Spenner is a very nice and reliable craftsman. We will recommend him with a clear conscience and with pleasure.

A very very good decision.
Excellent installation.
The alarm system is a top product.
Advice and installation were simply excellent.
Waiting time from order to installation took only a few days!
Fast and clean work.
Super service ...solution-oriented,
even if it was technically tricky.
I can only warmly recommend the company!!!!.
Also, all questions were answered in full, so that I can also cope with the technology without further ado.
In addition, you get telephone support for questions at any time and importantly, remote support is also possible.

Thanks
