I have a banana shaped polynuc as a result of its previous owner winding down on a ratchet strap -water gets ino the roof joint now but luckily the locating rim inside stops it going further- beware.....
All my main equipment that I use most is from Abelo..not sure what mk1/mk2 and mk3 is but I am sure it is not an Escort Turbo.. ..
The first boxes I bought where a few years back that come with the big deep roofs..the second lot where the new type with the slim comercial type roofs..I do not use those roofs but both style boxes are Brilliant..I have no water promblems at all during spring/summer and winter with healthy strong colonies ..I have the inspection board half out this time of the year and pushed in during winter..the only mould I have found up to date is from small fail8ng colonies half way through winter..apart from them I can't fault the Abelo hives.
