So sorry haven't noticed this post earlier :swear:
The controllers shown on
Ebay India looks like work on similar PCB inside them, as functions are same.
however red one looks horrible, even with having nice functions I would hide it instead of using it in front of guest

Also the cheap plastic feel cabinet which has ON/OFF button looks horrible, looks like made by some geeks at very low cost
similar to emergency lights assembled inside transparent box, which are made in corner of a shop, but sells like hell.
Only one product looks
professionally built, go for it, ask the seller a question if needed, I may also hunt similar in local store and
if its available will post details, but this would not be in a week or two.
For eBay use the discount coupon and save 5-10% and enjoy it.
