    ended up buying 2 of these, one is for my Astrolux MF 02sV2 and one for my MF 04s, these are compatible with a few other flashlights too. Shipping was fast and the extension works well

    excellent extension tube. much better balance. great battery carrier. good threads. good price. i dont like the texturing as much as the origional but it's okay.

    It works although sometimes it doesn't make contact well and I think it's because they now use aluminum instead of brass in the junction of the battery carrier out there. Everything else works fine. only as a comment to say that better packaging is needed because it risks being damaged in transport

    The extension tube is really nice on the Astrolux MF02. It is machined well with good black anodising and square cut threads. The knurling is block-style and quite different from the knurling of the other battery tubes. The new battery carrier is made of aluminium and weighs only 59g while the brass version weighs 137g. So it is only half the weight with the same performance otherwise. You can see in the fotos that the contact plate looks different than on the product fotos. The battery tube is easy to install, fits and works well. The packaging should be improved because my battery tube had a dent on one end that I needed to cut away.

    Awesome! Now I can use 8x 30Q batteries to double the run-time for my Mateminco MT70 Plus! 4h30m ~ 5h last time I tested on continuous HIGH mode. Another benefit is that now the big flashlight is weight-balanced. Much easier to use with the shoulder strap.

    Daca forma tesita de pe tub s-ar alinia cu Butonul de pornire ar arata mai bine.

    works well but needs a little more quality control. one of the battery holders rubs the sides of the tube and didn't make proper contact. with a little sand paper it was easily fixed.

    delivered in good time,this aftermarket extension tube is a welcome addition to anyone with a Mateminco or Astrolux flashlight that takes the usual 4x 18650 cells, it doubles the capacity of batteries

    Finally the light duration that fits. I use the tube on a MF 01 or on a MF 04S. The MF 04S thus becomes equal to a Lumintop GT. A few sharp edges had to be reworked.
