Friendly, competent, and helpful. Thank goodness there are still specialty shops in Waldtrudering.

We recently had a burglary alarm system installed by the company Mattis. From the on-site consultation, offer, and implementation, everything was top-notch. Especially the installation by technician Becker was unmatched in execution, communication, and cleanliness. A company with its team like this is extremely rare to find. Congratulations from a delighted customer!!!!!

Very competent advice and also high-quality locking systems that have always served us well both in business and privately, and we greatly appreciated the good and honest advice. In every good business, in the end, it’s not just about the price, but what you get for it - you can always do everything cheaper - but whether the customer ultimately benefits from it is another question - all businesses that offer on the higher-quality side know this, and we have come to appreciate it more than ever. Mattis is one of those.

The advice on security technology was excellent. The company was not focused on selling me as much as possible, but clearly stated what makes sense and what does not. The installation was also very good. The work was done quickly, cleanly, neatly, friendly, and conscientiously.

I have been working as property management for years and am more than satisfied with the company. Whether it's for doorbell labels, making copies of keys, issues with locking cylinders, door stops, overhead door closers... Always friendly, correct, and absolutely reliable.
