This is easy enough to use and many personal trainers recommend this. It's a LOT easier to do if you are slender and on the small side. I'm a former football player and weigh 230 lbs. at 6 foot 3 inches tall ... so rolling that type of frame isn't easy. My hands just about fit the handles, which measure 4.5 inches each. The handles have a hard foam grip, which may cause fatigue after a while, which is why I wear gloves when doing this. The actual wheel is only 2 inches across. (18 cm) This adds a little challenge keeping it stable.
The worst part about this product is putting it together. It comes in 3 parts ... the long handle, the wheel and a foam grip which must be slid onto the metal bar after the wheel is placed on it. This seems easy but it took a long time of twisting and turning the grip to get it fully onto the bar. This was an exercise in itself. Once its on, its not going anywhere!
Packing this in a suitcase or bag could be hard because once you get that grip on, it's there. This is a great product for hotel rooms where you don't want to touch your hands on a filthy carpet while doing push-ups. Its also good for the office. Something you may consider is this may be a good pre or post workout tool to use to roll out your muscles as an alternative to a foam roller. It feels good on the legs and if someone else rolls out your back and shoulders.
Keep in mind that the wheel is made of hard rubber and it will leave marks on hardwood floors. Especially ones with a shine to them. This will likely buff out but be cautious. I do like the Adidas branding on the ends with red caps and white logos and the grips feature the Adidas 3 stripe as well. I'd always go name brand with fitness equipment, even though this was made in China.
