This isn't this model by the way, but it illustrates the situation.
So why am I delighted ? because the ***** thing kept falling over behind me and cracking me on the back of my knees ! believe me, my legs weren't the only thing that were black and blue - the air was too ! but as it was in working order I didn't feel justified in replacing it, so I've waited patiently for nearly 8 years, and in some considerable pain for it to pack up.
Another reason I'm delighted is - I'm getting a replacement for FREE ! as I said nothing to do with the lifetime guarantee, I'm going to choose another model later today and will tell you how I'm getting it for free tomorrow.
Can't get more Frugal than free .............
