> 3 dayIt works as expected. Pretty easy to read once you adjust the contrast. Rated at 4 stars because it comes with zero documentation. They do seem to be pretty standard so I was able to get it working using an example for Arduino online.

> 3 dayNo issues with this. Using it with Arduino Uno. Almost plug and play.

> 3 dayThe first was defective. The second is great. The I2C address in your program may need to be adjusted

> 3 dayWas a little skeptical having read some reviews regarding poor solder connections, especially as the pictured device in the product description clearly shows solder bridges on the I.C. so I inspected it very carefully before proceeding. Workmanship as good as other quality and expensive components. Everything worked as advertised. The LED jumper disables the back-light and the display contrast is very clear. I also ordered the 2 extra I2C boards from the same vendor (Hiletgo) and both tested perfectly. Same results on other devices from them.

> 3 dayDisplay worked as expected. I had trouble initially setting up in code as I have only used 2x20s in the past. I sent an email to HiLetgo and they responded with all the info I needed. I highly recommend.

> 3 dayIt works nicely and seems to be good value for the low cost. I had to play around finding the right library file to get it to work-the one on Last Minute Engineers works fine, and they have a nice tutorial to help get it running.

Greater than one weekThese are nice display modules with 2 wire I2c interface. Display is sharp and bright. Easy to read with or without the backlight. I tried to get a picture but my phone camera did not do it justice.

> 3 dayI hooked this 20 x 4 line display up as my temperature monitor. Works great and in programming all you need to know is the lines you are displaying (4) and the max characters you display (20). I blew one with walking on my rug and zaping it with static discharge, now i get square characters.
