Customer Reviews
Great value for money
Spent a while looking for the right Pinnacle 5/16" and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.

Happy with SuperSaver AU
Have bought Pinnacle before and always been happy. Great price on SuperSaver AU and delivery was fast. Arrived perfectly packaged. Works flawlessly from day one.
Fast delivery and perfect condition
Fast delivery and exactly what I ordered. Very happy with this.
Outstanding value
Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.
Good buy — fast shipping
Really good value — compared it to similar products at twice the price and there is very little difference in quality. Fast shipping and arrived in perfect condition.
