Following the post-hike cleaning recommendations direct by conversation with Sawyer's customer service (vinegar and/or hot-water) did not clear the filter. Though Sawyer Warranty Dept asks you to package well(bubble-wrap/shock absorption inside sturdy cardboard).. If they do repair it - they return it without bubble wrap, and it'll even get loose, banging from side to side in the return box (excessive shock for a filter). You're left with a filter of unknown reliability - which if you call for replacement - they'll do nothing. Skip buying a toss and replace filter - for buying from a Company who'll send you a free filter/parts on issue, like Platypus.
I'm a 10 handicapper -- and generally recommend this device. I live in cold climate -- so I've been using it on an indoor golf simulator and roughly the stats are similar. I've captured swings from a few different folks and results are as expected.
Two things I like about it compared with other devices --- it is can capture shaft rotation & uncock.
I wish it had an option to immediately after the swing to show swing stats for a few seconds. (unless I'm missing how to setup this option) On the range, I'd like to work on stuff and know immediately the results. (instead of having to stop, analyze, look -- then go back to measure)
