Really well, felt very sturdy and stable when in use, Never once felt unsafe under the car while using them. Would Highly recommend, you can see them in use in my MX-5 videos there some covering a coolant leak repair and one covering doing an oil change. I noticed the other there is a big discount on the lift kit at halfords right now, you get a trolley jack, these axle stands and a creeper board all in one for far less than buying them all seperate, wish I had bought that now although it wasn't on offer at the time.
