Its a very professional and well designed site. I like the overall look & feel and is another in the line of excellent looking dotnetnuke sites. If I have some criticisms, they are minor, in no apparent order:
1. Its not immediately apparent on the homepage what the site is actually for. I gather by looking a little closer its for medical instruments? Are you selling them, recommending them, building them etc...
Maybe this will be more apparent to someone who is working in this field. I would have a think about how you are presenting your content on the homepage and what a naive user will think when looking at the site. Content can be rotated if you want to keep it consise yet still display a range of options to users. There are modules that exist to do content rotation.
A good book on site usability is "Dont Make Me Think" - cant remember who its by!
- I will note that the content is presented very well on other pages. My criticism on this point is mainly with the homepage.
- e.g. these pages are presented excellently
http://www.eclipsesys.com/Equipment...ault.aspx, http://www.eclipsesys.com/PartsLoca...fault.aspx its immediately apparent what they are for and you can locate content within them quickly.
Something I like about the content on the site is that the pages don't suffer from the "tumbleweed effect", where a page has too little content to warrant having its own page. Each page does have its own identity and is appropriately consise yet has enough information to be useful. The only one I really find fault with under this criteria is the homepage.
2. The FavIcon could be changed, its dotnetnuke default at the moment. This is a 10 minute job and can be done with this site
http://www.favicon.co.uk/ 3. You could use sIFR to add a custom font to the header above the image on the homepage, this would allow you to add a custom font, yet leave the text in there for search engines. Do a google search on "Futuristic Fonts" and you will find hundreds of great free fonts for download. The sIFR tutorial with dotnetnuke is issue 10 or 11 I think. sIFR 3 is now out which I've used and found it simpler and more powerful than sIFR 2.
Finally Im not a bit advocate of flash, but I almost expected the image on the homepage to move! Even a slight modification such as keep the planet/sun image static but animate the text very subtly can reduce the static effect that looks a bit oldschool.
Ok, that sounded quite critical, that's not my intention - I actually think the site is really good, but these are my immediate opinions which I thought might be helpful!
