Hello D,<br /><br /> Welcome to our community. I will be glad to help you out. These skins are basically images, but to use the skin you need the software Wisbar Advance and Desktop. Their official site is
www.lakeridgesoftware.com<br /><br />WM2003se devices never experience much lag but a few WM5 devices report slowing down. Download the trial version from their website and feel free to test it out in your device. Almost all skins are Free in their forums but the software is priced around $20 USD. Currently we are teaming up with them and planned to offer the software for a lower price. Contact us if you are keen to purchase.<br /><br />Regards<br />Carty..
