    Sadly some of the threaded spikes had damaged threads making it hard to screw on and adjust the disks. Once resolved was straightforward to use. Time will tell if it holds weight of shed workshop without settling / distorting.

  2. Richard Shepherd (verified owner) –

    Works just as advertised. Easy and efficient.

  3. Mark H. (verified owner) –

    Excellent product, really well engineered. Easy to fit and discs spun effortlessly.
    We were setting up on a 6 inch gradient on rough ground and very simple to get level.
    20mm drill bit to pilot the holes a very good tip.
    Might be worth sending with protective caps for the spikes. When upside down with spikes pointing up, be very careful not to slip!

    The video talks about turning over the frame with the discs etc attached. Using 6×2 and with a 12 disc frame this is not really possible safely for a single person. I thus had to build the frame on top of the QuickJack components, which made matters a little more complicated. But overall very happy with the solution, which I had selected as simpler, cheaper and more environmentally friendly than a traditional concrete base.

    Very clever and simple solution and a good alternative to concrete.

  12. Tristan C. (verified owner) –

    Bought the 12×8 kit. Brilliant solution for a shed base installation. A big time saver vs pavers or concrete plus it keeps the whole shed off the ground and away from water. Highly recommend.

  13. Anonymous (verified owner) –

    Very good value and quality

  14. Stephen B. (verified owner) –

    Excellent alternative to a concrete or slab base

  15. Norman Joseph (verified owner) –

    First time I have used this system and glad because the ground sloped a lot more than expected so these base kits made the job a lot easier than trying to lay a concrete base.

  16. Christina (verified owner) –

    Great bit of kit. Easy installation and much cheaper than concrete or slabs.
