your going to get A LOT of opinions. I've had excellent luck with the ipv series. I've had the ipv, ipv2, ipv3, and now I have the ipv4S. They have NEVER given me ONE BIT of trouble! The ipv4s goes up to 120 watts and can be upgraded for free online with the newest firmware and wattage increase from the computer. it fires down to .1 ohms. it is also temperature controlled and will fire kanthal, titanium, and nickle wire. it has a easy to use no screw battery replacement area on the side which takes two 18650 batteries which are rechargeable. I usually with vaping heavily get three full days out of my batteries before I have to recharge. I use the intelli- charger 4 (amazon) which charges 4 batteries at once so I got 4 batteries and rotate them. I always have two pre charged and NEVER have to wait on charging. the ipv4S in person Is NOT boxy it carries well and is fairly light. it has several memory settings you can set for your favorite atomizers. it fires comfortably. the ipv4s has the new YIHI computer chips in it and is extremely accurate. I've checked this myself several times and it's always dead on. the temperature control will keep you from getting burnt dry hits. HONNESTLY, for the price this is a EXCELLENT choice of unit for under 70 dollars(I paid 130 for the ipv3) so yes, it's quite a deal. it has a adjustable 510 connection with a aeration to allow atomizers to get air under them. it is also vented very well on the bottom of the unit. the display on the ipv4S is crisp and clear and easily read. it's also more sturdy than you think.(mines had a few drops and never suffered) I have NOT had any chipping or peeling paint. where you grip the mod, the side battery area is slightly rubberized and allows for a good hold. I HIGHLY RECOMMEND this mod. for the price, it's packed full of goodies. as I mentioned I've NEVER had any issues with ANY of the ipv series I've owned. in fact they ALL still work. the manufacturer is Pioneer 4 You. it comes with the usb cable for upgrading. if you do price comparisons, I think you will agree, you get a LOT for the price. I do hope this helps. best wishes on your vaping journey.
