Perfect trained bowler kit. The order has been as expected. The same key for both of us.
Ok
It's perfect!
Hello, I received the barrels (6) within a very correct time I installed everything and it's perfect and I also have enough double key (6 part. part barrels)
Good cylinder. I bought two identical cylinders with the same key and I received the 2 with 12 identical keys, they are security and very soft when opening and turning the latch. They are not the cheapest but they will be the best quality and reliability of the seller. I communicated through aliexpress messages with the seller to make sure that they would deliver the two bowlers with the same identity holders and they answered well.
Correctmeasures .....mo Tada and working perfectly. A good product
Answers quickly. Had ordered incorrectly himself, could change the order via chat.
Thanks to the seller for the super contact and for the fast delivery, looks good quality, to do with the time the strength, no problem to install them because European standard, I highly recommend.
Very precise description with the different dimensions Adapts perfectly to my front door Very satisfied with my purchase👍👍👍
parfait
Super
Nice quality I took 7 single-key barrels I have a lot of key suddenly😅
Excellent quality locks and entirely in accordance with the offered. It is a pity that so many keys are added. I had ordered 4 cylinders with 1 and the same Key for all four, but got 4x6 = 24 separate identical keys. Shame about that extra material that now needs to be put away safely to keep an overview of who may or may not have a Key.
All fine, thank you very much very fast delivery
This door cylinder seems of good quality. All keys, including those ordered extra, work very well. I highly recommend this product and this shop, very responsive to Knife requests. Thank you!
Top the top well received my seller item, super nice and a real professional
Quality is good in general. It works. But the finishing is not as good as the removed cylinder from European producer.
Super seller. I managed to brake one of the locks wich was part of system of four with the same key I ordered before and I asked if is possible to send me another one to work with the same master key. He sent me the code of my locks and by this code I ordered the new one wich is working perfectly. Thank you for all your help once again. The best seller 😊
