Query: This thing LASTS!!!

I love this pump! I had an electric pump that I just didn't feel provided me with enough suction. This pump works great! The suction is completely up to you and in my opinion much better then even the expensive rental pump I had. It's efficient, mobile, easy to clean and use. By far the best part however is how you can beat the crap out of it and it will keep on going. I've had this pump for nearly a year, use it almost daily, have taken it everywhere with me, I've dropped it, beat it in a diaper bag, washed it in the dishwasher hundreds of times now, all of this and this beast still works like a champ! If you aren't planning on pumping a ton and maybe even if you are (who doesn't need a back up?!) This pump lives up to the test of time!
