## Questions & Answers

**Q: Can anyone explain why 38% of reviews are 5 star and 31% are 1 star? Is it just that the product is not waterproof?**
A: I am not sure, but I have bought two. Neither lasted 90 days. They sent me a set of new batteries, but that did not solve the problem. It is perhaps the moisture. I discarded them as the 2 I was able to figure out the light level of the area in question. The 5 star/1 star differential probably is how often they are used.

**Q: What does partial shade mean?  How many hours of sun is "partial shade."  Why aren't the designations made clear?**
A: Approximately 2-6 hours of sun.  Part shade means more shade than sun during the 12 hours the test runs.  Part sun means more sun than shade during the 12 hours the test runs. It's not as definitive as many of us would like and depends on where you live.  In Texas where it is very hot with intense sun, part shade definitely means afternoon shade.

**Q: I don't see any numbers or dials on it. How do you know how many hours of direct sunlight?**
A: It has a 12 hours preset which starts when you turn it on.  It will flash the full 12 hours and then end with a solid light next to your sunlight factor.  you really want to set it just before sunrise to get the most accurate reading.

**Q: I have the suncalc. Does anyone else flash and not give a solid led reading?**
A: If it doesn’t do what the directions say I would return it.  Our first one was broken or the battery was dead because it wouldn’t even turn on.  The second one did exactly what the instructions called for.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good value
*by N***E on March 15, 2023*

Given the price, you can't expect lab accuracy. It's a good value.A couple of comments:1 - You need to scrub the probes before using. There is a scrubby sponge in the box.2 - Succulents are having their day in the sun, but this unit will not work for gritty succulent soil. Not enough soil contact, probably, and certainly you can't make mud of it for pH.3 - Light is measured in LUX, which is really not a measurement of anything plants need. You can get the same measurement on your cell phone. But a light meter that measures PPFD is quite expensive. LUX can be a good proxy measurement for outdoor sunlight, but for plants under grow lights like houseplants and seedlings, it's pretty useless.

### ⭐⭐⭐⭐⭐ WORKS!
*by S***L on April 25, 2024*

I always have the hardest time figuring out if different parts of my yard are good for certain plants sun-wise. This Sun Calc is great. I've tried it in multiple parts of my yard and it reads accurately. One thing I noticed other reviewers saying is it did not give an accurate read and I want to give my suggestions for troubleshooting. First, this needs 12 full hours of LIGHT to read accurately. So it has to be put out at sunrise and picked up 12 hours later. If you put it out later and the full 12 hours run into evening darkness then that will throw off the reading. If it is a very cloudy day, that will throw off the reading. So do it on a day that is average for your area and make sure the sun calc is there for a full 12 hours of daylight. If none of that works, then you may have a faulty product. If you get a good product then this is AMAZING.

### ⭐ Seems Accurate - Poor Durability
*by J***A on September 2, 2023*

Updating Review - I took this out to use it this year and it did not work. I opened it up to change the batteries and the ones that came with it leaked and eroded the thin terminal metal so this no longer works. I thought it would be okay to store indoors but I guess the batteries need to be removed when not in use. This was a complete waste of money.Updating review - The company responded to me with the sun ranges for each category. Posting here if you are interested.Full Sun – 6 + hoursPartial Sun – 4-6 hoursPartial Shade – 1.5 – 4 hoursFull Shade – Less than 1.5 hoursI placed this in an area that I expected to be partial sun and that is what the meter showed. It is easy to assemble, turn on, and use. It is also easy to tell when it is still measuring sunlight.It would be nice it the calculated level lit up as a solid light instead of a flashing light. With how quick it flashed I had to cover the two closest bulbs to make sure I was seeing the correct one light up.They also have poor product support. I reached out to see how they calculate the sunlight levels for each category. Depending on where you look, you can get different hour levels for the different categories of sun. Some also measure morning, mid-day, and evening sun differently. The company never responded to me.
