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.
