I have both of these and the LHR75e is becoming my favorite very quickly. It is sooo much quieter and it's a lot easier to roll up the cord then a air hose. ( call me lazy ) Both do a great job
I too have both and also find the LHR75E a little more convenient than the air version. Such as always having to be somewhere that has an compressor. But they both work great.
I only have the electric version and I am glad I bought it, there are so many areas on vehicles that this gem can be used. It pays for itself. Now I just need to get the smaller ones and I will be able to detail HotWheels cars!
I love my LHR75E. It does correction really quickly and light to carry. I used to use my GG6 with a smaller backing plate for the same job and found that tiring for lower panels
