Good strong metal fence post extender. Fast delivery service & received in good condition.

### ⭐ Poorly Informed..
*by A***N on 5 July 2020*

Nothing wrong with the product, however if the company had been honest with me and told me it would be 2 weeks before i was likely to see it. I would have got one sooner from local outlet, also it would cost me more that half of what i paid for it to send it back.... Buyer beware.....
