      Works great in circuit

      Overall: 5 out of 5

      I have not used this model but I did use the previous model very often. This is a wonderful tool. It is so much easier to test caps in circuit without the need to unsolder. Does not affect other components. You still must unsolder one leg if other caps are in parallel. This works great for bad caps in the vertical or horz. circuit of CRT tv's. I used to use an O-scope and check ripple but this is so much faster and doesn't require the tv to be powered up. ( used to get zapped but not now ) I highly recommend this item.
