Interpet Long Airstone, 300 mm

It looks great, but it doesn't quite do what i expected.Instead of bubbles out of the whole length, they just come out of the first quarter of the stone, really large and fast, and just one tiny stream further down. It did NOT produce a curtain of bubbles, as you can see in the photos.A real shame, would have been better off making a splitter and using three or four small round ones.UPDATE: Feb 2021After a month, it started to allow air through in a couple more places, and slowly but surely, it ended up doing what it was supposed to.It now has air coming out of it all the way along, and looks great, as well as helping the fish breathe.If it had done this at the start, I wouldn't have given it 3 stars, but am now giving it 5 as it really is doing a great job finally.

Complete waste of money am so pleased only paid 2.49 ... put it in worked great for the first day .. came home next day and was only one bubble so looked at the airstone and it had actually crumbled so pipe came off .. had to quickly hoover bottom of tank to ensure the blue bits were gone as didn't want fish to eat them

Doesn't work at all! Bubbles just come out where the little plastic bit goes into the stone.Gutted. Was looking forward to getting this tank sorted for a friend

Works beautiful in my fish tankYou do need to blow though the air stone when you first put it inValue for money

Threw it out before I had a chance to take a photoDO NOT BUY!!! Unless you want to buy a replacement every 2 weeks or so.Had in my freshwater tank since the 28th May. Its now the 9th June. Fell apart and crumbled like dust in the tank after I spotted the black air hose plug had come apart from the blue air bar. DO NOT BUY

The airstone looked lovely when it arrived. I soaked it for two hours as advised but when put in the aquarium there was not a wall of bubbles as stated. One stream of large bubbles at end of stone then a small stream of bubbles half way down. Not very pleased at all so ended up in the bin.

Came snapped in half, very disappointed. Delivered opend rite in the bin.Really do not recommend this item, maybe if you seen it in a fish shop and it was all in once peace maybe it would be worth it.

Love the item, works very well. Packaging- large box for a small item. Surely smaller boxes for small items would be a money saver for the company.
