Perfect gift — loved it
Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.
Arrived well packed
The Selleys Spakfilla is a solid buy. I was a bit unsure about the size from the photos but it is perfect in person. Delivery was faster than expected. Very satisfied with this purchase.
Better than expected
No issues at all. Fast delivery and exactly as described.
Great value for money
Spent a while looking for the right Selleys Spakfilla 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.
