BUY LOCAL, NOT IMPORTED
Apart from it giving you a warm fuzzy feeling inside supporting local Industry, there is a huge upside to not spending your hard earned off-shore. You'll get a much better spa cover if you buy Australian made.
The exception to that is covers imported from the US. They are relatively expensive but generally of a high standard.
In contrast, the majority of spa covers are imported from ...... you know where. If you get 2 years out of one of these covers before it disintegrates, then you're on par.
There is so much more to creating a high performance spa cover than simply copying the design. The Chinese are excellent imitators but the years of research and trial and error put in by local manufacturers are not always evident to the inexperienced eye.
Levels of UV protection, heat sealing techniques, proper resistant underside, thread quality, hinging, stitching techniques etc are sadly lacking in the cheap imports ( and now also sadly in most of the local Manufacturers who are trying to compete with the Chinese for price ).
We used to say that if something was Japanese made, then it was rubbish. Now everyone wants a Toyota. Perhaps in time the Chinese will create a superior spa cover but for now, let the buyer beware.
Unfortunately, nearly all new spas sold today in Australia are manufactured in China and so to is the cover that comes with it. It's only when you need to replace your cover that you will have a clear choice as to what quality it should be.
