Is anyone using Investec High 10 or High 5 issue 2?

I like that the accounts offer 'almost' the best rate, without having to keep constantly moving money around from one bonus paying account to another.

Would anyone who uses either account recommend them?

I note there is a minimum balance of £25k. Is it possible to add additional deposits to your account after opening it? Is there any minimum deposit amount if the required £25k has already been deposited (i.e. could you deposit an extra £50 after opening it ?)

Also is withdrawing money relatively hassle free (other than having to give notice!)?
