Satisfied customer

Had been looking at the Pinnacle M5 for a couple of months. Pinnacle Hardware build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.

Absolutely love it!

Had the Pinnacle M5 on my wishlist for a few weeks and finally pulled the trigger. Arrived in 2 days which was a nice surprise. Build quality is solid and exactly what the photos showed. My partner uses it every day now and has already asked me to grab another one as a gift.

Best buy of the year

Ordered Thursday and had it by Saturday. Packaging was really good — nothing moved around. Works exactly as expected and the price was well below what I saw in stores.
