they've been up a week and a noticeable reduction in birds in my mini orchard, but the bird nestling in my hanging flower pot is not intimidated.

Noticeable positive change in color depth and sharpness. Major improvement over cables that were in use. Decent price quick delivery.

I saw improvement in a few days.  My Lab is able to go from a sitting/laying position to a standing position with much more ease.

I seem to notice a slight increase in acceleration and gas mileage.  Time will tell if they will really last the lifetime of the car.

These took a few days to really start working but they have definitely reduced the amount of ants I was seeing in my apartment. Only see one once in a while now.

Only been using a little over a week, but can see the difference, especially in leafy veggies and fresh berries.

It has reduced our engine's noise output at cruising speeds and seems to increase acceleration ability after a week of use.

I got this at a reduced price to leave a review.  I seem to be sleeping better and not as stressed as I was before I started taking these.

Water quality has improved. And sediment appears to be breaking down better.

I have had the crystals for almost 3 weeks now. I'm not seeing any difference since we have started using them.  We don't sleep any better, my anxiety and stress are not any better.  Maybe it takes longer than 3 weeks. I'm keeping an open mind that it will get better.  They do give off a nice soft light.

After about 2 weeks now the shies feel great; reduced knee and foot pain at the end of the day.  One minor complaint is that they don't breath very well.
