Rated 5 out of 5 stars
I used this for years and it was very helpful to me and seemingly free of problems. I usually have my laptop/surface hooked up to a 32" or greater television, rather than using the small on-board monitor, which often made images appear too small for me to make out from any distance, especially without my glasses. Now it has been dropped for no apparent reason (incompatibility with updates?) and I cannot find a suitable replacement. I never experienced an issue with this add-on and I would be delighted to see it return.
