I bought this for two handed swings. I don't have particularly large hands but cannot get all fingers in for swings, and it's really uncomfortable for goblet curls and the horns start to bend in straight away. I contacted bulldog to see if perhaps a manufacturing error, but I was advised it was standard. 24kg is too heavy for me to use one handed, and returning back a 24kg kettlebell is hassle. Workmanship between horns and ball was also disappointing and not the smoothest. Pretty disappointing overall.
I'm as impressed as the rest. Nice kettlebell, Comfortable textured grip, room for two hands.
No dramas with delivery.
Happy customer.
Initially I was concerned as only 2 of the kettlebells arrived, however, i noticed a note from the company on the boxes explaining they may get delivered on seperate says. Great work from the company in ensuring customers dont worry, the kettlebells are great
Hight quality gear delivered quickly
Great buy
