I have experienced some famous MN Straps and the Elastic loop does wear its name very well because it is more Elastic!
Not having a buckle when you turn around your wrist is a bit disturbing at first but you get use to it. Comfort is here and no additional height is added to your watch as it is attached to the case like a normal strap.
I have a 16.5cm wrist size and went with a 130mm. Sometimes during the day maybe when my wrist was swollen it felt a bit tight, maybe next time I'll try a 140. With the right size for your wrist it will definitely be a 5 stars!
