By manufacturer the intended pressure reducer (4 bar) is the part of a dangerous, EXTREMELY effective tool. It is advised extreme caution. This thing has even close to the ground yet a focal radius of about one meter spits like crazy (talk to someone no longer works) and burns in geschildertem radius in fractions of a second small weeds completely gone. Note: Be sure safety shoes, waterproof clothing and goggles. Hot sand and small stones, and glowing plant parts flying around. Take care that the flying stuff otherwise Kindle in the garden. As a precaution, keep a watering can with water nearby ready. In gutters you have to expect that the road surface melts. Plastic Beetabgrenzungen (sidewalls) melt even at a relatively large distance. Not too close to hedges burn with dry wood below.
Conclusion: class device as long as you comply with all safety precautions (too little towards it rejected). Unfortunately, the device does not have a lighter, but that's just fine with a cheap long lighter and the acquisition is therefore cheaper than similar devices with attached, not always well-functioning, piezo igniter and the combination is more universal. (Z. B. Cilio Lighter "Turbo Flexi")
One point deduction because it is not pointed enough to the tremendous impact.
