I did not communicate with the seller, there was no need. Duplicates a little less than expected, the colors of the bolts are a little different, but most importantly everything works. Made the whole family copies in a matter of moments. On the lock, I checked all work. The seller is definitely worth recommending.

Very light weight. In the hand you feel that it's not expensive. Works well. Batteries in the kit do not go. In the kit 5 color keys! The parcel arrived quickly! Thank you! Seller well done

All declared functions perform, reads and writes RFID 125 kHz. Who has tablets that need to be tightly applied to the groove will not work. Recorded without problems smart ring jakcom R4.

Mail to St. Petersburg was delivered in 20 days. Packed well. The body of the device is slightly luftitis, the key was sewn for verification, everything works. Thank you!
