As with any purchase, take time to look at the product information and ask questions of the vendor. See who else offers a similar product and see if they will give you references. Talk to someone using the product to develop your own opinion. Make a side by side comparison if possible and make your decision. Personally I went with the Optistart 8 as mentioned here previously. I got to talk to a couple of salons who had purchased them and gave good reports on their results. I installed 64 of them this evening in 2 of my Tanses beds. 1st impression, looks good all
lamps came on as usual. Time will tell on this 'improvement'.
