Used this product happily for about two weeks

Used this product happily for about two weeks, then it fell off the windshield. No problem, I thought, I'll just reapply. I had another one of these (different manufacturer) for five years and periodically I would have to reapply the suction cup. So I did.. and about 10 minutes later, it fell off. Odd, I thought. I made sure the glass was clean, moistened the suction cup, reapplied. 10 minutes later, falls off again. Then again. And again. Won't stay on for more than about 3 seconds now.

Not sure what's up with this, but I'm returning it.

I've used this just shy of two months and is a great value. No issues.

I should have heeded the other reviews - this filter works great about for two weeks until it just stops working altogether. After about a week of use, I washed it out with vinegar solution exactly as the manual instructed. It continued working great for a couple of days after I washed it until one day, when I turned it on, nothing happened. If you read the other reviews you will see I'm not the only one who had this problem. Don't waste your money on a piece of plastic that will only work for two weeks. Buy something else!

This product worked great when we purchased it two months ago, but it just stopped working last week out of the blue.

After use for two weeks it looks good quality and no sound, heat or other problems

The pedometer worked well- kept track of miles, kilometers, steps, miles, and calories- until it broke two weeks after I got it.

I've only been using it for a couple of weeks but I'm very happy with how well it works :- )

Awesome... for the two weeks it worked! This thing just completely died with no warning. Works really well until that point.

It lasted about two weeks and it started to leak from the regulator.

A day ago, I would have put this as five stars.  I LOVE this device and it worked very well for two weeks, both in salt and chlorine water.  After uploading last night, it died suddenly and it won't turn on.  Kudos to Amazon and Finis for great support - I contacted both and they were both willing to give a replacement (Amazon as under 30 days would have offered a refund).  I didn't ask Finis whether refund was possible.  This device made me want to swim and I really, really hope that the replacement works well.  Will update the review once I know.  Also, fyi, I found the quality of the sound perfectly fine for both music and podcasts/books.  I had read that the latter was less clear but I have found it fine.  It works best with the crawl (head underwater at all times) but I can follow even with breast stroke.  An amazing product if the technical glitches can be worked out.

I enjoyed this product for 2 weeks then for some reason it quite working.  We brought it into the main part of the house and left it over night then tried it again and it worked inside the warm part of the house.  I fear if we keep it and try to use it again in the cold part of the house it will quit again when we need it so this is why i am returning it.  I am hoping it is just a fluke and the product is good.

I enjoyed the product for the 2 week period it worked, however the product became less enjoyable when it stopped responding.
*edit: I was able to get a very quick and friendly response from customer service and was issued a full refund*

I got this to give my little energetic cat a fighting chance at some food - my portlier cat tends to eat everything that's placed in the dish, but is too lazy to exert effort for food. It was pretty effective, but, unfortunately, it busted about two weeks after purchase.
