Rolson Alarm Padlock Review


The Rolson 66857 Alarm Padlock sells well in online stores, and online buyers have given this padlock an 85% buyer satisfaction rating, which overall is a very good online buyer rating.

Like any alarm padlock, it serves two purposes. Firstly the padlock makes it more difficult for thieves to break in, and secondly should they persist, triggers an alarm if the padlock is interfered with.

Buyers said the lock was strong, and that the siren is certainly loud enough to send any potential thieves running.

You can buy these as a single, in a pack of 2 or a pack of 3.

Padlocks with any type of alarm cost around £8-£20, depending on the quality, and mainly on the length of the shackle, with longer shackles being slightly more expensive.

This Rolson model costs on average £11-£13 depending on where you make your purchase.
