Disappointed with this Dry Lube product! Ordered on Friday and received on Wednesday by Royal Mail at 3:15pm this was obviously not the fault of the sender. When I received it I didn’t expect it to be a thick and oily substance! I followed the instructions to the letter but found it difficult inserting the round nozzle into a horizontal and serrated lock. The lock was installed less than 6 months ago and it is recommended a dry lube be used at least every 6 months by one of their recommended companies and I chose this company. The lock on my door was starting to stick and so I purchased the dry lube from their recommended company. Unfortunately, this product did not alleviate the problem and the lock is now completely stuck and I am now unable to lock/unlock the door. I would like to add that on the bottle of dry lube and with the package received it does not state the product number and just states dry lube so therefore I am unsure if it is the correct product.
