## Before you buy

- Listing details are inconsistent or unconfirmed: the main details give material as Chrome, while the product specification says Zinc Alloy and another description says aluminum alloy. The listed weight of 25 Grams conflicts with the A+ specification of Approx. 1288g / 45.4oz, and the overall dimensions differ in scope from the separate panel measurements. Confirm the exact material, weight and dimensions for the selected listing before purchase. The listing's broad gate and door compatibility claims do not confirm fit for a particular door or glass installation.

## A good fit for

## Less suited to

- Buyers who need verified material or weight details, given the conflicting listing specifications.
- People looking for an electronic or connected smart lock, features not stated for this mechanical model.

## Customer feedback

Customer feedback reports positive impressions of build quality, sturdiness, fit and installation, with some customers saying the code and lock worked as expected. Instructions drew criticism and ease of use was not consistent across reports. For buyers, that makes careful setup and checking door fit especially relevant. The listing describes a mechanical, battery-free keypad, but those stated features do not resolve the reported usability and instruction concerns.

- Positive themes: Customers report that the code and lock function as expected.
- Negative themes: Some customers criticise the instructions.
