Pros & Cons
Pros
Excellent product, delivered on time for a reasonable price. Used all 100 leds and all worked. It's far better than the original configuration. Would buy again. And 6.
Cons
Even with properly installed current limiting resistors, these leds get very dim after a few days of operation. After long periods of use, they go into a constant blinking or just dim - indicating failure.
The price is right, but the frustration of replacing them is very inconvenient. The info says 1500-2000 mcd, but there is no way these are close to that! Do not buy. A complete rip off.
Highlights
Quality
In any case i thought the quality and price were very good and i would recommend them anywhere a flashing display is desired

Price
If you calculate it right ๐ price was resonable as well for the qualiy received
Packaging/appearance
On one side it was about a 1mm too long so i snipped off the very end of that one with wire cutter
Competitiveness
Run for days on a 3v coin cell too
Heads up though if you are using a solderless breadboard it can get messy
They can run directly off of the cr2032 batteries the button cell batteries that are about the sizeshape of a quarter

If they arent lighting the color that you want it might be that the leads and the resistors are touching

One could possible go with a lower value resistor any they would be even brighter

While the number of possible displays was much greater with the arduino adding the hardware and software seemed like too much work for a simple project

They worked just fine but it seemed like the flashing rate was too high and maybe the overall brightness of a rapidly flashing display was too much to be on all of the time
