The spike was hard work to knock into the ground, make sure that you have plenty of pieces of wood to protect the spike top as you hammer it. I am 180cm tall and the dryer is too low. It spins easily so there is less chance of it falling over. It is very good quality and will probably last a long time.
These are excellent rotary dryers. The action to open and close them is effortless and despite the size the dryer is really light and easy to handle. The spike is simple to install, doesn't need any concrete and so far - I've never had a problem. I've found these dryers to be very robust and very efficient.
