I haven't used that particular model number in the way of triggers but we have 2 pairs of the yn 602 triggers that have had a heck of a lot of use both firing remote strobes and also acting as remote shutter releases with a change of cord. Replaced the non rechargeable batteries in the triggers and recharged the AAAs in the receivers many times, no sign of them dying or falling apart and they have simply worked consistently over the years. I believe that you get more than you pay for with some of their products, especially considering they were priced around the $30.00 point for each pair.
