Trusted by Team Collett

We are proud to share Team Collett’s feedback about the new Sanderson™ Hay Steamer.

Laura Collett MBE is a World Class British Equestrian and a British Olympic Team Gold Medallist from Tokyo 2021. Her incredible career highlights include Winning Badminton Horse Trials 5* 2022 on LONDON 52 with the lowest finishing score in the history of the event (21.4).

We look forward to working with Laura and her team as she continues her incredible journey.

"We intended to use the Sanderson to steam for one horse, but as soon as it arrived we found it so easy we started steaming for 3!"

"Everyone at team Collett has loved using the Sanderson hay steamer. The different settings are easy to use, and it's not only energy and time efficient but also much safer, with the steamer turning off once it’s finished. It puts us all at ease knowing the hay is being consistently steamed to remove any bacteria and dust throughout, with all the guesswork taken out of the process. And most importantly the horses love it!"

"We used to steam individual hay nets. Now we steam the entire bale and then load the hay nets straight from the Sanderson hay steamer. It works really well! Somehow it’s much easier to make hay nets with the softer steamed hay, and for sure it’s less dusty for us."

"We love the quality, it's soft and steamed all the way through the bale, not too wet not too dry, just right"

"The different steam cycles are so useful."

"The digital screen is so helpful, it's super easy to follow to start steaming and tells you where you are in the steam cycle. It’s great!"

"We love that you can hear the steam jets working their magic inside the chest!"
