My discretion in the most versatile belay device on the market. Suitable without restriction for indoors and outdoors - so far very favorable. Handling simple, functional diversity is more than adequate. Sure it's course - but only if the security technique is mastered. Anyone who is unsure: can not wait to show by an experienced climber extensively or attend a relevant course (eg: from DAV). Just read the manual ranges in a washing machine, but not climbing!
