- Product arrived right, took a while because of the post office strike, I was taxed by customs, but other than that the product works right and as described by the seller emilianolds,15/09/2020
- Great source liked it and already started using the only problem is that it doesn't come with wire to plug in the output what should come in, compact, lightweight and practical font fits in any very good corner. mrcfer,15/08/2020
- received quickly, seems well made and decent quality checked output against calibrated meter and really is pretty accurate. came with eu plug so changed to fused uk plug. can be change to 110v supply if required but using 230v at present. current control can limit flow and doesnt just shut down output. very happy with this for the money.
