Whatís the eBay item number, out of curiosity? I didnít find it.
No reason to think they wonít work out, assuming you get on well with the design (everyoneís different). They are made to a very high standard. I sold mine mainly because I had better things to do with the money, but they performed very well Ė amazingly so for something so small and light.
LotuTec isnít worth much to me. Itís not magic and you still have to clean the lenses occasionally.
