tenga flip or fleshlight trainer?

Hi looking to get my OH either a tenga flip http://www.lovehoney.co.uk/product.cfm?p=14734 or fleshlight trainer http://www.lovehoney.co.uk/product.cfm?p=13190 and wanted any advice as to which is better, he has delayed ejaculation and so im hoping that one of these will help get him used to feel of coming inside as opposed to his hand or my mouth without the pressure.

Thanks

Out of all my strokers, the original white TENGA Flip Hole offers the closest approximation of vaginal sex, so that would be my recommendation
