Arrived ahead of the specified time which, was nice.

Had some superficial marks to the bezel, but overall cannot complain. A great light for anyone looking to purchase one - just be aware that the tan is slightly different across the light owing to different materials.

Very happy with the product and with xtremetactical- thank you!

Great Service and communication.

Contacted them after ordering, as the products can take up to 10 days to post and they let me know when they were expecting it, and within a few days it had turned up. Unfortunately the M640DF doesn’t come with a tail switch, though this is not XtremeTacticals issue.
Very happy with the product.
