Yes, the Marstar site is very outdated and goes against many things of modern web design. In fact I'd be weary about using it.
1. When you sign up for an account the site generates your password. This would indicate to me the password is stored in their system without going through a 1 way hash. When you create a password the site should run your password through a function that hashes it to something else, this way if their system is ever hacked your password can't be recovered from the hacked data. E.g: "password" is hashed to something like this ax92l44mdwo3fgHx009.
2. If you change your marstar password you can change it to literally anything. A system is only as secure as it's weakest password. My password is now 'a'. Yup, just the letter a.
3. Auto-playing videos. This hurts site SEO a lot.
4. No built in search. Marstar just piggybacks off a google search. That's pretty lame and useless.
5. Product pages are lacking sort functions.
6. No shipping estimates.
Need I go on? Enter your information into this site all you want, but it probably shouldn't be trusted for much. I do this stuff for a living. Whoever wrote the Marstar site should be fired.
