22.7 litre helium tank for 100 balloons Seller was very responsive and professional in her dealings. Tested the helium tank and balloon was able to float. Wanted to test how long was the ballon able to float but couldn’t keep the timing as busy with work. But estimates from 7 hours as I inflated balloon at a abt 10 am and saw the balloon on the ground abt 6pm. My last stop to the kitchen was as 3pm and was still afloat and to take note that I only inflate the ballon not to its full size. So Highly recommended to purchase helium tanks from seller if you need it. Thanks much seller !!!
