The look Great BUT!
by Member #703720 verified purchaser
Three out of the four that i ordered arrived with several of the segments soldered in backwards. I spent many hours chasing my butt trying to figure out why my code was not working. Come to find out (as i said) several of them had segments in wrong. Other than this issue, so far i like the way they look.

Visible at least 100 feet away!
by Member #1151506 verified purchaser
I love using these for a scoreboard system for outdoor tailgating and corn-hole games, but usable for any highly visible and bright user-interface. Get (2) per scoreboard, or get (4) and make a huge clock!Always get the backpack module for each digit, to reduce your wiring needs and complexity of pins, and allow simple daisy chaining of each item.
PRO TIPS: A large solder and attachment area, so 1) Wipe a bit of Rosin Soldering Flux on all mating surfaces, 2) Dab a solder bead onto each connecting pin for the display and backpack, 3) Align both pieces together, and fuse melt and feed a little more solder to bridge the gap while its molten. SOLID! Nothing else out there like these babies!

Easy to work with....
by TheBatman verified purchaser
Having no experience with 7 segments before I found these are very easy to work with as long as you get the SparkFun Large Digit Driver that goes with it up above. Very bright, changes numbers nicely, good instructions with the driver hookup, and durable product.
I would buy again. Only suggestion is to add more color options.

Not Suitable for Outdoor
by Member #841961 verified purchaser
Although these things work very well for my application, an outdoor radar speed sign, they are failing on a regular basis. I have them mounted in a plastic weather tight enclosure which is reset into a larger enclosure. In the cooler temperatures in the Northwest, they lasted 7 months. In the hotter temperatures here in So. Calif. (around 90 F) they fail within weeks. I'm not impressed.

temperature sensitivity
by Member #1442626 verified purchaser
Where those are really good for indoor, they suffer from heat. I got them on the outside running stadium since spring. First hotter day killed them without warning. Was debugging that whole Christmas, and indeed, its the leds are what went bad. Maybe inside the beautiful box the temperatures goes over all thresholds.
Dear sparkfun, I really value your products, do you mind to enhance description of this product, clearly stating it is indoor - room temperatures only? or ideally, add exact temperatures this can work in?

We will try to get temperature data from the manufacturer and will update the product page once we have that.

So far so good.
by Member #866245 verified purchaser
I ordered 4 of these to make a large timer and so far they are working great. I wish they were a bit brighter in terms of light, and a bit less pink-ish in color though!

RED LED Large
by Member #699387 verified purchaser
The product is good. So far it worked for what I wanted to do. The segments are bright I will buy more shortly.
Best large 7-Segment Digit ever bought
by Member #77687 verified purchaser
Very bright, easy to mount, good quality.Perfect for me in conjunction with the SparkFun Large Display Driver.I coverd my 4 digit display with red acryl-glass. Even on sunny days you can read the digits from a hundred feet away.
Bright, clean
by Member #1169363 verified purchaser
Very good - bright, responsive. I'll order more.
Work great!
by Member #48288 verified purchaser
I have used a bunch of these and when used with the 7-Seg LED Driver board that Sparkfun offers, getting it up and running was a breeze.
Perfect for my project!
by Member #1260306 verified purchaser
Was pleasantly surprised when I saw that it was 12VDC. Now I don't need to step down the voltage on my project.
Very Good

Fun little Item, slight quality issues
by J3 verified purchaser
I enjoyed working with these components. Paired with the driver port that Sparkfun offers they are very easy to control. My only reservation is that I ordered six of these and two of them had issues with their decimal. On one the resistor for the decimal was soldered on poorly to where the solder bypassed the resistor making brighter than the segments. The other didn't work because the solder wasn't properly joining the resistor to the circuit. Thankfully I needed to remove all the decimals for my project.
Perfect product
by Member #500661 verified purchaser
I like them a lot, you should offer in blue, white and yellowIt will be a best seller
Large display with even brightness
by xImran verified purchaser
I was looking for large display and this suited just fine for my project. The brightness is uniform and is visible from a far.
Progress with Large 7-segment display
by Member #1887121 verified purchaser
I ordered and received four of the large 7 segment displays with their associated drivers. I soldered the driver boards to the back of each. I then discovered that I should have applied some insulating tape to the rear of the display drivers before soldering them to the back of the display boards. I was disappointed to learn this after soldering. I tried a couple of methods of inserting insulating material in between the driver boards and the displays. I was not successful.
Fortunately my boards do work properly without the insulation. Due to twisting when mounted they may fail.
I was able to modify the example sketch to display a fixed value from an ESP 32 Dev board. I was then able to modify the sketch to receive data via ESP NOW from another ESP 32 Dev board.
My ultimate goal is that the large displays will act as a remote display for a Batcher project that I made with another ESP 32 connected to a flow meter. The Batcher will show a running total on its own display and also transmit this value to the other ESP 32 and the large digit displays. This will allow me to view the running total from either display. This is used to mix "Batches" of spray mixture for use on my farm crops.
I haven't decided on an enclosure for the four large displays. Maybe some type of picture frame could be modified for this.

Beside owning two 2 dogs and a kitten, this is the #4 Best.Excellent product and super great docs you supplied.
Great display
by Member #132163 verified purchaser
This display is great. Very visible. I've used a couple of them for an educational counting board for my sons and they love it.
I have your (big) number...
by RocketGuy verified purchaser
These are hilariously large and once you get them solidly connected to the driver boards, they're easy to use. I found the connection to the driver boards needed soldering to really be reliable, but what else is new?
Decently bright, and now I just have to figure out what I'm going to do with them...

Works great
by Darrell G verified purchaser
Bought six of these to make a giant clock for the back of a large meeting room. Speakers now have no trouble telling what time it is.
One segment on one of the digits was not soldered on one end, but it took longer to warm up my iron than it did to fix that.
