Purchased the Vacmaster Cardio 54 to compliment my indoor cycling set-up. It arrived extremely quickly (within 48hrs). Powerful and cooling fan ideal to regulate my body temperature during sessions - if you are Zwifting downhill with the Cardio 54 on you may need a gilet - ha ha ha! On a serious note it does actually feel like you are outside and the 3x speed fan should be more than ample for the hardest of indoor sessions. The remote control works really well controlling on / off and the 3x speeds. Highly recommend this product to fellow indoor cyclists and / or if you have a home gym to help cool you down and circulate the air.
