I’ve tried a bunch of hacks including wiping the board with WD40 and have since moved on to glass write boards when and where I can.
I’ve had times in my career where I didn’t have $200 to spend, and the hardware store option is great, but $200, in the end, is a small price to pay if you use the board for more than a year.
I've had mine for almost 3 years and it's holding up just fine using EXPO markers (also listed in the post). I haven't counted an exact number of times I've used it, but it's a lot. Hundreds of times for sure. I just make sure to clean it semi-regularly which takes about 20 seconds once a month. Maybe yours wore out quickly because you didn't clean it?
But it looks like they've discontinued the larger sheets? That's a shame.
Dunno how useful this is as I have no idea how to identify the actual brand/manufacturer of the "good" ones...
The whiteboard that I've been using for the past six or seven years cost me $15 - $20 depending on whatever the exchange rate was back then. I could go measure it, but it's about 40 cm tall by 60 cm wide.
Google around for 8 foot x 4 foot whiteboards (244cm x 122cm). The pre-made solutions are all in the ~$200 USD range.
I don't mind spending money but it's hard to pass up $15 worth of materials at home depot and 20 minutes of work instead of buying a pre-made whiteboard for $200.
If anyone is curious, even ~3 years later with a decent amount of usage it works great.
