Rated 5 out of 5 by from Great product Concrete in 100x100 post holders, easy to use, sturdy construction. Only in a few days so I can’t comment on reliability yet.

Rated 3 out of 5 by from too small I bought these to support 2x 6 foot 100mm fence posts. Now if some one has has even picked up such a big post, you know how heavy it is! The posts slide straight in and you then tighten then with the bolts, but the issue is that, as the posts are so heavy and tall and this support only holds 6 inches of the bottom post out of the 6 foot - it doesn't hold it that stable and the post wobbles! Now this size might be ok for a 70mm post, but 100mm support should have been a bit taller to be able to control/hold the post more. But I don't think there is any alternative out there, so we might as well use this :)

Rated 4 out of 5 by from Quite good - bolt may rust Used these for a few fence supports and when concreted in they are solid but would need additional support at either end of a run of fence panels like a wall or brick pier - I've attached them to the house and an existing concrete post.. They're just not strong enough to rely on alone and I wouldn't trust them alone against any strong winds.. Unfortunately the bolt used to retain the post isn't great either and has already started to show signs of rust. A better quality bolt and more effective securing mechanism would make it better. They're also quite pricey at £19 a pair but should will make it easier to change posts in the future, even if a new bolt is needed.

Rated 3 out of 5 by from Best place to get this post Tried all the local DIY stores trying to get this type of post but they either did not stock them or they were expensive. The other make of post at the other stores did seem better constucted though but in the end price won out

Rated 3 out of 5 by from Good for Fence Repair Bought two of these to replace waterlogged rotten posts. Good for fixing where ground may be too wet to sink a wooden post into the ground. Expensive but posts might last better than a post sunk into a wet ground.

Rated 4 out of 5 by from Makes the Job easier I've used these post supports for several DIY fence jobs. Really easy to use and provide a very solid base. The only downside is that they are quite expensive. Makes it a high cost job if you're doing a long run. Still if you're happy to trade effort for cost then you can't go wrong.
