Item was as described, and very fast delivery!

5 stars across the board for every seller rating category, and I would buy from this seller again. And per my request, the capacitors were also very well packed for safe delivery.

Obtainium have been a very helpful seller to me.

In recent times I have had a few items go astray enroute to my address in Australia. This seller was most helpful & encouraging, regarding the onward tracking & eventual safe delivery of this item. This item's arrival in good condition was a joy to me as, it was a rare part that fitted my military comms. Well done seller. I would gladly recommend this seller to all potential buyers.
